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. 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 Intangible Assets Intangible assets consist primarily of acquired patents. The Company acquired $1,400,000 1 2. Goodwill Goodwill was acquired with the reverse acquisition discussed in Note 1 2. not first not no Long-Lived Assets Long-lived assets, such as property and equipment and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not Company first not third 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 - The carrying value approximates fair value due to the short maturity of these items. Notes payable - The fair value of the Company's notes payable has been estimated by the Company based upon the liability's characteristics, including interest rate. The carrying value approximates fair value. 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: December 31, 201 7 201 6 Options 2,950,262 76,577 Warrants 32,728 65,228 Series A convertible preferred stock 115,000 115,000 Series B convertible preferred stock - 41,842,241 Convertible debentures 84,103,256 26,716,467 Total potentially dilutive shares 87,201,246 68,815,513 Note - Share information for the periods has been retroactively adjusted to reflect the June 28, 2017 one 300 Research and Development Research and development costs are expensed as incurred. Research and development costs amounted to approximately $ 456,000 $301,000 December 31, 2017 2016, 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. Prior to the reverse acquisition, Coretec elected to be taxed as a Partnership for federal and state income tax purposes. Under this election substantially all of the profits, losses, credits and deductions of Coretec were passed through to the individual members. Therefore, prior to the reverse acquisition, no Prior to the reverse acquisition, 3DIcon ’s tax benefits were 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 not Recent Accounting Pronouncements The following is a summary of recent accounting pronouncements that are relevant to the Company: In January 2016, ASU No. 2016 01, Financial Instruments – Overall (Subtopic 825 10 2016 01” 2016 01 2016 01 December 15, 2017. 2016 01 not In August 2016, ASU No. 2016 15, Statement of Cash Flows (Topic 230 2016 15” 2016 15 eight 2016 15 December 15, 2017, 2016 15 not In February 2016, No. 2016 02, Leases (Topic 842 December 15, 2018, may The FASB has issued ASU 2014 09, Revenue from Contracts with Customers 605 July 9, 2015, No. 2014 09 December 15, 2016 December 15, 2017. not In January 2017, 2017 01, Business Combinations (Topic 805 not not December 15, 2017, not In January 2017, 2017 04, Intangibles – Goodwill and Other (Topic 350 2 2, December 15, 2019, January 1, 2017 not Uncertainties The Company has realized a cumulative net loss of $2,593,337 June 2, 2015) December 31, 2017, 1,904,514, no The ability of the Company to continue as a going concern depends on the successful completion of the Company's capital raising efforts to fund the development of its planned products.

Use of Estimates, Policy [Policy Text Block]	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.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment are recorded at cost.

Current Assets and Current Liabilities, Policy [Policy Text Block]	Current assets and current liabilities - The carrying value approximates fair value due to the short maturity of these items.
Notes Payable, Policy [Policy Text Block]	Notes payable - The fair value of the Company's notes payable has been estimated by the Company based upon the liability's characteristics, including interest rate. The carrying value approximates fair value.
Earnings Per Share, Policy [Policy Text Block]	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: December 31, 201 7 201 6 Options 2,950,262 76,577 Warrants 32,728 65,228 Series A convertible preferred stock 115,000 115,000 Series B convertible preferred stock - 41,842,241 Convertible debentures 84,103,256 26,716,467 Total potentially dilutive shares 87,201,246 68,815,513 Note - Share information for the periods has been retroactively adjusted to reflect the June 28, 2017 one 300

Income Tax, Policy [Policy Text Block]	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. Prior to the reverse acquisition, Coretec elected to be taxed as a Partnership for federal and state income tax purposes. Under this election substantially all of the profits, losses, credits and deductions of Coretec were passed through to the individual members. Therefore, prior to the reverse acquisition, no Prior to the reverse acquisition, 3DIcon ’s tax benefits were fully offset by a valuation allowance due to the uncertainty that the deferred tax assets would be realized.
