Use of Estimates, Policy [Policy Text Block]

Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Marketable Securities, Policy [Policy Text Block]

Marketable Securities

The Company’s marketable securities consist of investments in U.S. Treasury bills with original maturities greater than three months from the date of purchase. These securities are classified as held-to-maturity debt securities because the Company has the positive intent and ability to hold them to maturity. Held-to-maturity securities are recorded at amortized cost, adjusted for any allowance for credit losses, with securities having remaining maturities of less than one year classified as current on the unaudited condensed consolidated balance sheets.

The Company evaluates held-to-maturity securities for expected credit losses using a qualitative assessment methodology. As of June 30, 2026 and December 31, 2025, no allowance for credit losses was required. U.S. Treasury bills are backed by the full faith and credit of the U.S. government and are considered to have minimal credit risk.

The Company excludes accrued interest from the amortized cost basis of held-to-maturity debt securities. Accrued interest totaled $59,111 and $117,949 as of June 30, 2026 and December 31, 2025, respectively. Accrued interest is included in prepaid expenses and other current assets on the unaudited condensed consolidated balance sheets. The Company recognizes interest income through accretion of the discount from the purchase price to par value over the holding period. Discount accretion is recognized in interest income on the unaudited condensed consolidated statements of operations.

The following tables summarize the gross unrealized gains and losses related to the Company’s held-to-maturity marketable securities:

	As of June 30, 2026
			Gross Unrealized		Gross Unrealized
	Amortized Cost		Gains		(losses)		Fair Value
Marketable securities
U.S. Treasury bills	$	6,922,222	$	56,550	$	-	$	6,978,772
Total marketable securities	$	6,922,222	$	56,550	$	-	$	6,978,772

	As of December 31, 2025
			Gross Unrealized		Gross Unrealized
	Amortized Cost		Gains		(losses)		Fair Value
Marketable securities
U.S. Treasury bills	$	21,277,609	$	98,006	$	-	$	21,375,615
Total marketable securities	$	21,277,609	$	98,006	$	-	$	21,375,615

Fair value is measured using Level 2 inputs (prices for similar assets or liabilities that are directly or indirectly observable in the marketplace). All held-to-maturity U.S. Treasury bills had remaining maturities of less than one year as of June 30, 2026. Purchases and maturities of held-to-maturity securities are presented within cash flows from investing activities on the unaudited condensed consolidated statements of cash flows.

Inventory, Policy [Policy Text Block]

Inventories

Inventories are stated at the lower of cost or net realizable value, with cost determined on the first-in, first-out (“FIFO”) method. The establishment of allowances for excess and obsolete inventories is based on historical usage and estimated exposure on specific inventory items. Inventories consisted of the following:

	June 30,		December 31,
	2026		2025

Inventories - Current Portion
Raw materials	$	298,834	$	292,566
Work in process		211,260		103,215
Finished goods		835,662		700,284
Total Inventories - Current Portion		1,345,756		1,096,065
Inventories - Long-term
Raw materials		512,565		415,383
Finished goods		552,836		-
Total Inventories - Long-term		1,065,401		415,383
Total Inventories	$	2,411,157	$	1,511,448

Raw materials include components used to manufacture the Company’s capital equipment and consumable products. Long-term inventories represent raw materials and finished goods that the Company does not expect to consume in production or sell within twelve months. The inventories currently classified as long-term are not subject to expiration.

The Company utilizes significant estimates in determining the realizable value of its inventories, including the future revenue forecasts that will result in product sales. These estimates have a corresponding impact on the inventory values recorded as of June 30, 2026 and December 31, 2025. Management continually evaluates the likelihood of future sales based on current economic conditions, expiration timing of products, and product design changes prior to sale of product on hand. If actual conditions are less favorable than those the Company has projected, it may need to increase its reserves for excess and obsolete inventories. Any increases in the Company’s reserves will adversely impact its results of operations. The establishment of a reserve for excess and obsolete inventories establishes a new cost basis in the inventory. Future sales of inventory on hand at June 30, 2026 will result in recognition of cost of sales based on initial inventory costs, net of reserves taken for expected realization values. For the three months ended June 30, 2026 and 2025, the Company recorded inventory reserve expense of $213,758 and $214,719, respectively. For the six months ended June 30, 2026 and 2025, the Company recorded inventory reserve expense of $269,566 and $214,719, respectively.

Lessee, Leases [Policy Text Block]

Leases

At the inception of a contract, the Company determines whether the contract is or contains a lease based on all relevant facts and circumstances. Leases with a term greater than 12 months are recognized on the unaudited condensed consolidated balance sheets as ROU assets and corresponding current and non-current lease liabilities. Amounts expected to be paid within 12 months are classified as current lease liabilities, with the remainder classified as non-current lease liabilities. The Company has elected not to recognize leases with terms of 12 months or less on the unaudited condensed consolidated balance sheets. Lease payments for short-term leases are recognized as an expense on a straight-line basis over the lease term. The Company includes lease option extensions in the assessment of the lease arrangement when it is reasonably certain the option will be exercised.

ROU assets and the corresponding lease liabilities are recorded based on the present value of lease payments to be made over the lease term. The discount rate used to calculate the present value is the rate implicit in the lease, or if not readily determinable, the Company’s incremental borrowing rate. The Company’s incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. Certain adjustments to the ROU asset may be required for items such as initial direct costs or incentives received. See Note 5 for additional disclosure on leases.

For all asset classes of its leases, the Company has elected to account for the lease and non-lease components together for all classes of underlying assets.

Other Assets [Policy Text Block]

Other Assets

Other assets on the unaudited condensed consolidated balance sheets include security deposits related to the Company’s operating leases, an equity investment, and a derivative asset. Other assets consisted of the following:

	June 30,		December 31,
	2026		2025

Security deposit	$	41,097	$	60,488
Equity investment		69,560		69,560
Derivative asset		-		56,243
	$	110,657	$	186,291

The equity investment of $69,560 is held at cost. There have been no impairment losses or observable price changes recognized for the six months ended June 30, 2026 and 2025.

Income Tax, Policy [Policy Text Block]

Income Taxes

Income taxes are recorded under the liability method. Deferred income taxes are provided for temporary differences between financial reporting and tax bases of assets and liabilities. Deferred tax assets are reduced by a valuation allowance to the extent the realization of the related deferred tax asset is not assured.

The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than not threshold, the amount recognized in the unaudited condensed consolidated financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency Exchange (Losses) Gains

As of June 30, 2026 and December 31, 2025, the Company had cash accounts denominated in Euros and Australian dollars, accounts payable that are denominated in Euros and Australian dollars, lease liabilities denominated in Euros, and accounts receivable denominated in Euros and Hungarian forint. These assets and liabilities have been remeasured into U.S. dollars at period-end exchange rates. Foreign currency exchange (loss) gain of $(683,434) and $1,285,261 for the three months ended June 30, 2026 and 2025, respectively, and $(281,024) and $1,159,493 for the six months ended June 30, 2026 and 2025, respectively, are included on the unaudited condensed consolidated statements of operations within other income (expense).

Royalties, Revenue Recognition [Policy Text Block]

Royalties

On June 1, 2012, the Company licensed certain intellectual property to a customer which included a royalty of 3% of product sales, subject to a minimum of $50,000 per year through 2028. The minimum guaranteed royalties were recognized upon the execution of the license agreement as these proceeds were not variable consideration. The remaining minimum royalty payments to be received, less the portion which represents future interest expected to be received within 12 months is included in Accounts receivable and the amounts expected to be received in future periods beyond 12 months are included in Accounts receivable, long term. Any royalties received in the future which are more than the minimum guaranteed royalty will be recognized when they are earned.

Derivatives, Policy [Policy Text Block]

Derivative Asset, Option Liabilities, and Warrant Liabilities

The Capital Commitment Agreement (“Agreement”) with GEM Global Yield LLC SCS (“GGY”) (discussed further in Note 8) meets the definition of a derivative and was recorded upon issuance within other assets on the unaudited condensed consolidated balance sheets at fair value. The derivative asset is revalued at each balance sheet date, with changes in fair value recorded on the unaudited condensed consolidated statements of operations as other income (expense). The Company estimates the fair value of the asset using the Monte Carlo Simulation model.

Also, in connection with the Agreement with GGY, the Company issued 5,700,000 options which were determined to qualify as liabilities in accordance with Accounting Standards Codification (“ASC”) 480-10, Distinguishing Liabilities from Equity and ASC 815-40, Derivatives and Hedging. Additionally, the Company issued warrants in connection with the equity raises in August and October 2023 (Note 9), where 2,100,568 warrants were determined to qualify as liabilities due to the exercise price being denominated in a currency other than the Company’s functional currency. The result of this accounting treatment is that the options and warrants are recorded upon issuance as liabilities on the unaudited condensed consolidated balance sheets at fair value and are revalued at each balance sheet date, with the change in fair value recorded on the unaudited condensed consolidated statements of operations as other income (expense). The Company estimates the fair value of the liabilities using the Black-Scholes pricing model.

See Notes 8 and 9 for further details and assumptions used in the Black-Scholes pricing model and Monte Carlo Simulation model.

Fair Value Measurement, Policy [Policy Text Block]

Fair Value Measurement

ASC 820, Fair Value Measurements, (“ASC 820”) provides guidance on the development and disclosure of fair value measurements. Under this accounting guidance, fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.

The accounting guidance classifies fair value measurements in one of the following three categories for disclosure purposes:

	Level 1:	Quoted prices in active markets for identical assets or liabilities.
	Level 2:	Inputs other than Level 1 prices for similar assets or liabilities that are directly or indirectly observable in the marketplace.
	Level 3:	Unobservable inputs which are supported by little or no market activity and values determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation.

The Company evaluates assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them for each reporting period. This determination requires significant judgments to be made by the Company.

The carrying value of financial assets and liabilities recorded at fair value is measured on a recurring or nonrecurring basis. Financial assets and liabilities measured on a non-recurring basis are those that are adjusted to fair value when a significant event occurs. The Company had no financial assets or liabilities carried and measured on a nonrecurring basis during the reporting periods. Financial assets and liabilities measured on a recurring basis are those that are adjusted to fair value each time a financial statement is prepared. The following tables present information about the Company’s financial assets and liabilities measured at fair value on a recurring basis, based on the fair value hierarchy:

	As of June 30, 2026
	Level 1		Level 2		Level 3		Total
Current Liabilities
Current portion of convertible notes (related party)	$	-	$	-	$	33,186,900	$	33,186,900
Option liabilities	$	-	$	-	$	4,286,736	$	4,286,736
Total Current Liabilities	$	-	$	-	$	37,473,636	$	37,473,636
Long-term Liabilities

Option liabilities	$	-	$	-	$	3,157,717	$	3,157,717
Total Current Liabilities	$	-	$	-	$	14,903,417	$	14,903,417
Long-term Liabilities
Convertible notes, net of current portion (related party)	$	-	$	-	$	13,268,500	$	13,268,500
Warrant liabilities	$	-	$	-	$	1,828,677	$	1,828,677
Total Long-term Liabilities	$	-	$	-	$	15,097,177	$	15,097,177

The convertible notes (related party) (Note 7), the derivative asset and option liabilities (Note 8), and the warrant liabilities (Note 9) are recognized at fair value on a recurring basis at June 30, 2026 and December 31, 2025, and are all classified as Level 3. There have been no transfers between levels. The Company estimates the fair value of the asset or liabilities using the Monte Carlo Simulation model or Black-Scholes pricing model.

See Notes 7, 8, and 9 for further details and assumptions used in the respective pricing model.

As of June 30, 2026 and December 31, 2025, the recorded values of cash and cash equivalents, prepaid expenses, accounts payable, and accrued expenses and other liabilities approximate their fair values due to the short-term nature of these items.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Pronouncements

The Company considers the applicability and impact of all Accounting Standard Updates (“ASUs”). ASUs not discussed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company’s unaudited condensed consolidated financial statements and related notes.

In July 2025, the Financial Accounting Standards Board (“FASB”) issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides a practical expedient for entities estimated expected credit losses on current accounts receivable and current contract assets arising from transactions under Topic 606. The practical expedient permits an entity to assume current conditions as of the balance sheet date that do not change for the remaining life of the current accounts receivable and current contract assets. The Company adopted this standard as of January 1, 2026, on a prospective basis and elected the practical expedient for all in scope current trade receivables and current contract assets. Adoption of the ASU did not have a material impact on the Company’s unaudited condensed consolidated financial statements.

In November 2024, the FASB issued ASU 2024-04, Debt – Debt with Conversion and Other Options (Subtopic 470-20), which amends ASC 470-20 to clarify the circumstances in which an entity is required to account for a settlement of a debt instrument as an induced conversion. The Company adopted this standard as of January 1, 2026, prospectively. Adoption of the ASU did not have a material impact on the Company’s unaudited condensed consolidated financial statements.

Recent Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40). The amendment requires disaggregated disclosure of income statement expenses for public business entities (“PBEs”). The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. The standard is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently assessing the potential impact of adopting this new guidance on our unaudited condensed consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities, which establishes recognition, measurement, and presentation guidance for government grants received by business entities, distinguishing between grants related to assets and grants related to income. The guidance requires a government grant to be recognized when it is probable that the entity will comply with the conditions of the grant and that the grant will be received. The standard is effective for fiscal years beginning after December 15, 2028, for public business entities, and after December 15, 2029, for all other entities, with early adoption permitted. The Company is currently assessing the potential impact of adopting this new guidance on our interim unaudited condensed consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which clarifies interim disclosure requirements and the applicability of Topic 270, resulting in a consolidated list of all interim disclosures required by U.S. GAAP. The amendments include a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The standard is effective for interim periods within fiscal years beginning after December 15, 2027, for public business entities, and after December 15, 2028, for all other entities, with early adoption permitted. The Company is currently assessing the potential impact of adopting this new guidance on our interim unaudited condensed consolidated financial statements and related disclosures.
