Accounting Policies [Abstract]
Nature Of Operations and Going Concern Policy [Policy Text Block]	Going Concern These condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. However, substantial doubt about the Company’s ability to continue as a going concern exists. The Company has incurred significant and recurring losses from operations for the past several years and, as of June 30, 2024, had an accumulated deficit of $175,161,987. The Company had cash and cash equivalents of $5,331,770 as of June 30, 2024, and needs to raise significant additional capital to meet its operating needs. The Company had short-term obligations of $4,618,511 and long-term operating lease obligations of $1,860,983 as of June 30, 2024. The Company does not expect to generate sufficient operating revenue to sustain its operations in the near term. During the six months ended June 30, 2024, the Company incurred negative cash flows from operations of $6,634,072. Although the Company has attempted to improve its cash flows from operations by bolstering revenues and continues to seek ways to generate revenue through business development activities, there is no guarantee that the Company will be able to improve its cash flows from operations sufficiently or achieve profitability in the near term. As a result of these conditions, substantial doubt exists about the Company’s ability to continue as a going concern within one year after the date these condensed consolidated financial statements are issued. The Company is evaluating alternatives to obtain the required additional funding to maintain future operations. These alternatives may include, but are not limited to, equity financing, issuing debt, entering into other financing arrangements, or monetizing operating businesses or assets. These possibilities, to the extent available, may be on terms that result in significant dilution to the Company’s existing stockholders or that result in the Company’s existing stockholders losing part or all of their investment. Despite these potential sources of funding, the Company may be unable to access financing or obtain additional liquidity when needed or under acceptable terms, if at all. If such financing or adequate funds from operations are not available, the Company would be forced to limit its business activities and the Company could default on existing payment obligations, which would have a material adverse effect on its financial condition and results of operations, and the Company may ultimately be required to cease its operations and liquidate its business. The Company’s condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern and do not include any adjustment relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The Company has prepared the condensed consolidated financial statements and related unaudited financial information in the notes in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim condensed consolidated financial statements. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These interim condensed consolidated financial statements reflect all adjustments consisting of normal recurring adjustments, which in the opinion of management, are necessary to present fairly the Company’s position, the results of its operations, and its cash flows for the interim periods. These interim condensed consolidated financial statements reflect all intercompany eliminations. These interim condensed consolidated financial statements should be read in conjunction with the annual consolidated financial statements and the notes thereto contained in the Annual Report on Form 10-K filed with the SEC on March 28, 2024. The nature of the Company’s business is such that the results of any interim period may not be indicative of the results to be expected for the entire year.
Use of Estimates, Policy [Policy Text Block]	Accounting Policies and Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and during the reporting period. Actual results could materially differ from those estimates. Estimates are used in the following areas, among others: variable consideration associated with revenue recognition, stock-based compensation expense, fair value of long-lived assets for impairment analyses, the valuation allowance included in the deferred income tax calculation, accrued expenses, and fair value of derivative liabilities. Note 1 to the annual consolidated financial statements contained in the Annual Report on Form 10-K filed with the SEC on March 28, 2024, describes the significant accounting policies and estimates used in preparation of the consolidated financial statements. There have been no material changes in the Company’s significant accounting policies during the six months ended June 30, 2024.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The Company had two wholly owned subsidiaries, Helomics Corporation and Skyline Medical, Inc. (“Skyline Medical”), as of June 30, 2024, and December 31, 2023, and for the three and six months ended June 30, 2024, and 2023. The condensed consolidated financial statements include the accounts of the Company and these wholly owned subsidiaries after elimination of intercompany transactions and balances as of June 30, 2024, and December 31, 2023, and for the three and six months ended June 30, 2024, and 2023.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of Credit Risk Financial instruments that subject the Company to credit risk primarily consist of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalent balances with high quality financial institutions and, consequently, the Company believes that such funds are subject to minimal credit risk. The Company is exposed to credit risk in the event of default by the financial institutions to the extent amounts recorded on the condensed consolidated balance sheets are in excess of insured limits. The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds. As of June 30, 2024, accounts receivable from a single customer represented 11% of the Company’s total accounts receivable. As of December 31, 2023, accounts receivable from a single customer represented 16% of the Company’s total accounts receivable.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (the “FASB”). Recently issued ASUs not listed below either were assessed and determined to be not applicable or are currently expected to have no impact on the condensed consolidated financial statements of the Company. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU updates reportable segment disclosures by expanding the frequency and extent of segment disclosures. This ASU is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The ASU requires the retrospective adoption method. Management is currently evaluating this ASU to determine its impact on the Company’s disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU requires more detailed income tax disclosures. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. This ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. Management is currently evaluating this ASU to determine its impact on the Company’s disclosures.
