Business Description and Basis of Presentation [Text Block] | Note 1 Business Organization, Nature of Business and Basis of Presentation Nature of Business The Coretec Group Inc. (the “Group”) (formerly 3DIcon Corporation) (“3DIcon”) was incorporated on August 11, 1995, under the laws of the State of Oklahoma as First Keating Corporation. The articles of incorporation were amended August 1, 2003 to change the name to 3DIcon Corporation. During 2001, First Keating Corporation began to focus on the development of 360-degree holographic technology. From January 1, 2001, 3DIcon’s primary activity has been the raising of capital in order to pursue its goal of becoming a significant participant in the development, commercialization and marketing of next generation 3D display technologies. Coretec Industries, LLC (“Coretec”), is a wholly owned subsidiary of the Group (collectively the “Company”). The Company is currently developing, testing, and providing new and/or improved technologies, products, and service solutions for energy-related industries including, but not limited to oil/gas, renewable energy, and distributed energy industries. Many of these technologies and products also have application for medical, electronic, photonic, display, and lighting markets among others. Early adoption of these technologies and products is anticipated in markets for energy storage (Li-ion batteries), renewable energy (BIPV), and electronics (Asset Monitoring). Reverse Acquisition On May 31, 2016, the Group entered into a Share Exchange Agreement (the “Share Exchange Agreement”) with Coretec and four Coretec members (the “Members”), which Members held all outstanding membership interests in Coretec. On September 30, 2016 (the “Closing Date”), the Group closed the transaction contemplated by the Share Exchange Agreement. Pursuant to the Share Exchange Agreement, the Members agreed to sell all their membership interests in Coretec to the Group in exchange for the Group’s issuance of an aggregate 4,760,872 shares of the Group’s Series B Convertible Preferred Stock to the Members (the “Exchange”). Coretec became a wholly owned subsidiary of the Group and the former Members beneficially owned approximately 65% of the Group’s common stock on a fully diluted basis on the Closing Date. Upon the closing of the Share Exchange Agreement, two of the Group’s Directors resigned and three new Directors associated with Coretec were nominated and elected, giving control of the board of directors to former Coretec Members. Basis of Presentation The accompanying condensed consolidated financial statements of the Company have been prepared without audit pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).

Business Description and Accounting Policies [Text Block] | Note 2 Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of the Group and its wholly owned subsidiary, Coretec. Intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of 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, expenses and the disclosure of contingent assets and liabilities. Actual results could differ from the estimates and assumptions used. Intangibles Intangible assets consist of purchased patents and capitalized website costs. Intangible assets are recorded at the fair value as of the date of acquisition, and intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives. Goodwill Goodwill was acquired with the reverse acquisition. The Company evaluates the carrying value of goodwill on an annual basis and if events occur or circumstances change that would more likely than not reduce the fair value of goodwill below its carrying amount. When assessing whether goodwill is impaired, management considers first a qualitative approach to evaluate whether it is more likely than not the fair value of the goodwill is below its carrying amount; if so, management considers a quantitative approach by analyzing changes in performance and market-based metrics as compared to those used at the time of the initial acquisition. For the periods presented, no impairment charges were recognized. Property and Equipment Property and equipment are recorded at cost. Depreciation is recorded over the estimated useful lives using the straight-line method. Maintenance and repairs are expensed as incurred; major improvements and betterments are capitalized. Estimated useful lives of property and equipment are as follows for the major classes of assets: Asset Description Estimated Lives (years) Furniture and fixtures 7 Equipment 7 Impairment of Long-Lived Assets Long-lived assets, such as intangibles, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. Fair Value of Financial Instruments The following methods and assumptions were used to estimate the fair value of each class of financial instrument held by the Company: Current assets and current liabilities - Notes payable Basic and Diluted Loss Per Common Share Basic loss per common share is computed by dividing net loss by the weighted average number of vested common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other instruments to issue common stock were exercised or converted into common stock. The following securities are excluded from the calculation of weighted average dilutive common shares because their inclusion would have been anti-dilutive: March 31, 2023 2022 Options 77,158,160 53,161,609 Warrants 132,514,000 142,604,000 Series A convertible preferred stock 115,000 115,000 Convertible debt 45,155,537 39,836,388 Total potentially dilutive shares 254,942,697 235,716,997 Research and Development Research and development costs are expensed as incurred. Income Taxes The Company accounts for income taxes under an asset and liability approach that requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s consolidated financial statements or tax returns. In estimating future tax consequences, the Company generally considers all expected future events other than enactments of changes in tax laws or rates. The effect on deferred tax assets and liabilities of a change in tax rates will be recognized as income or expense in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized. The Company’s tax benefits are fully offset by a valuation allowance due to the uncertainty that the deferred tax assets would be realized. Management considers the likelihood of changes by taxing authorities in its filed income tax returns and recognizes a liability for or discloses potential changes that management believes are more likely than not to occur upon examination by tax authorities. Management has not identified any uncertain tax positions in filed income tax returns that require recognition or disclosure in the accompanying consolidated financial statements. |

The agreement allows for holders to exchange their options for rule 144 common stock at an exchange rate of 0.6 shares per 1 option. Under the exchange agreement, 9,500,000 options have been exchanged for 5,700,000 shares of common stock as of March 31, 2023 and December 31, 2022. On October 22, 2020, the Board of Directors consented to satisfying accrued liabilities of vendors by issuing common stock from the 2018 Equity Incentive Plan from August 26, 2020 through September 1, 2021. The number of shares issued to satisfy a liability was determined by the average closing price for the fifteen (15) days prior to conversion at a discount rate of 50% to that fifteen (15) day average. On November 10, 2021, the Board of Directors consented to continue this practice through September 1, 2022. As part of this written consent, the Board of Directors included the use of both the 2018 and 2021 Equity Incentive Plans. On October 14, 2022 the Board of Directors further consented to extend this practice through September 1, 2023. The Company issued zero shares under this consent for the three months ended March 31, 2023 and 900,000 shares for the three months ended March 31, 2022 Warrants Warrants to subscribe for and purchase up to 3,000,000 shares of common stock at an exercise price of $0.052 per share were included under the terms of the DAF Credit Agreement.

Warrants granted under the terms of the DAF Credit Agreement total 2,814,000 as of March 31, 2023 and December 31, 2022. The estimated value of the warrants granted monthly, with each advance, is calculated using the Black-Scholes option pricing model. The expected dividend yield is based on the average annual dividend yield as of the grant date. Expected volatility is based on the historical volatility of our stock. The risk-free interest rate is based on the U.S. Treasury Constant Maturity rates as of the grant date. The expected life of the warrant is based on historical exercise behavior and expected future experience. The resulting estimated value of the warrant is used to proportionally allocate the fair value of the debt advance and the fair value of the warrants.

The pre-funded warrants will be exercisable immediately and may be exercised at any time until all of the pre-funded warrants are exercised in full. In addition, the Company agreed to issue to the placement agent (or its designees) warrants to purchase a number of shares equal to 8.0% of the aggregate number of shares and pre-funded warrant shares sold under the Purchase Agreement, or warrants to purchase an aggregate of up to 6,000,000 shares. The placement agent warrants generally will have the same terms as the warrants, except they will have an exercise price of $0.10. Warrants Summary There was no warrant activity for the three months ended March 31, 2023. The following table summarizes the Company’s warrants as of March 31, 2023: Weighted Weighted Average Average Remaining Aggregate Number of Exercise Life Intrinsic Warrants Price In Years Value Outstanding, March 31, 2023 132,514,000 $ 0.0555 3.384 $ 1,333,850 Options Stock options for employees, directors or consultants, are valued at the date of award, which does not precede the approval date, and compensation cost is recognized in the period the options are vested. The Company recognizes compensation expense for awards subject to graded vesting on a straight-line basis. Stock options generally become exercisable on the date of grant and expire based on the terms of each grant. The estimated fair value of options for common stock granted was determined using the Black-Scholes option pricing model. The expected dividend yield is based on the average annual dividend yield as of the grant date. Expected volatility is based on the historical volatility of our stock. The risk-free interest rate is based on the U.S. Treasury Constant Maturity rates as of the grant date. The expected life of the option is based on historical exercise behavior and expected future experience. On March 23, 2022, the Board of Directors of the Company consented to granting 950,000 options to new employee and a consultant. These options have an exercise price of the $0.055 and vest immediately.

Commitments and Contingencies Disclosure [Text Block] | Note 7 Commitments Litigation, Claims, and Assessments The Company may be involved in legal proceedings, claims and assessments arising in the ordinary course of business. In the opinion of management, such matters are currently not expected to have a material impact on the Company’s condensed consolidated financial statements. The Company records legal costs associated with loss contingencies as incurred and accrues for all probable and estimable settlements. North Dakota State University Sponsored Research Agreement The Company entered into a Sponsored Research Agreement (“SRA”) dated August 14, 2015 with North Dakota State University Research Foundation (“NDSU/RF”). With the proposed research for this project, NDSU/RF planned to make prototypical compounds and materials from CHS and CHS derivatives with the potential; 1) to act as efficient photoactive materials for solar cells, 2) to serve in electro active devices for optimization of current and voltage performance, 3) to perform at high levels of efficiency as silicon anodes in lightweight batteries (silicon has more than 11 times the capacity of carbon in the ubiquitous carbon based batteries), and, 4) to be incorporated into specialty inks for printed electronics applications. The research was conducted August 14, 2015 through August 31, 2016. The Company agreed to reimburse NDSU/RF for all costs incurred in performing the research up to a maximum amount of $70,000. On June 7, 2016 the Company and NDSU/RF mutually agreed to amend the SRA. Under the terms of the amendment the term was extended to June 30, 2017 and the consideration was increased by $120,000 to a maximum amount of $190,000. As of December 31, 2022, the remaining balance of the SRA to be paid under the terms of the agreement is $93,578. As of December 31, 2022, and pursuant to the SRA, Coretec was in arrears on the payment of that obligation. Accordingly, as of December 31, 2022, Coretec would be considered in default under the SRA because of the unpaid obligations, which could allow NDSU/RF to exercise various options under the SRA, including an option to terminate the SRA if Coretec does not cure the default within 10 business days after receiving written notice by NDSU/RF. Due to Coretec’s belief that certain obligations of NDSU/RF were unsatisfied, Coretec has actively communicated with NDSU/RF in order to determine what obligations are owed and what actions all parties are required to take, and will agree to take, in furtherance of the SRA. In connection with such objective, Coretec has sent NDSU/RF a detailed communication setting forth, among other things, the basis for its belief that (i) the payment obligation was not due to NDSU/RF; and (ii) NDSU/RF does not have the right to enforce a default. Coretec did not attempt communication or receive communication from NDSU/RF during the year three months ended March 31, 2023. As of the date of this report, there have been no legal proceedings initiated in connection with the SRA. However, no assurances can be made that the prior communications between the parties will result in a resolution or that legal proceedings will not be initiated in the future. Real property leases The Company is leasing office and laboratory space in Ann Arbor, Michigan. On May 1, 2022, the Company entered into an annual lease for corporate office space. The annual office rent obligation is $42,000 payable in equal monthly installments. On December 14, 2021, the Company entered into an annual lease of a wet laboratory in the same facility as the Company’s office headquarters. The Company renewed the wet laboratory lease under the same terms for the calendar year of 2023. The annual rent obligation is $12,600 payable in equal monthly installments. Rent expense for the operating leases was $13,650 and $4,707 for the three months ended March 31, 2023 and 2022, respectively. |
