(the “Group”) (formerly 3DIcon “3DIcon” August 11, 1995, August 1, 2003 3DIcon 2001, 360 January 1, 2001, 3DIcon’s 3D Coretec Industries, LLC (“Coretec”), a wholly owned subsidiary of the Group (collectively the “Company”), was organized on June 2, 2015 not Reverse Acquisition On May 31, 2016, four September 30, 2016 ( 4,760,872 65% two three 65% one Basis of Presentation Under accounting principles generally accepted in the United States of America (“U.S. GAAP”), the acquisition is treated as a “reverse acquisition” under the purchase method of accounting. The consolidated statements of operations herein reflect the historical results of Coretec prior to the completion of the reverse acquisition since it was determined to be the accounting acquirer, and do not 3DIcon 3DIcon’s September 30, 2016 Principles of Consolidation The consolidated balance sheets as of December 31, 2019 2018 December 31, 2019 2018 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. Goodwill Goodwill was acquired with the reverse acquisition discussed in Note 1. 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 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 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: December 31, 2019 201 8 Options 21,716,557 216,557 Warrants 570,000 1,061 Series A convertible preferred stock 115,000 115,000 Convertible debt 13,11,457 289,804,783 Total potentially dilutive shares 35,523,014 290,137,401 Research and Development Research and development costs are expensed as incurred. Research and development costs amounted to approximately $80,000 $85,000 December 31, 2019 2018, 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 not Recent Accounting Pronouncements The Company has implemented all new accounting pronouncements that are in effect and that may not The following is a summary of recent accounting pronouncements that are relevant to the Company: The FASB has issued ASU 2014 12, Compensation - Stock Compensation (ASC Topic 718 not December 15, 2015. not In February 2016, No. 2016 02, Leases (Topic 842 ) December 15, 2018, January 1, 2019, 842 not 12 two no The FASB has issued ASU2014 09, Revenue from Contracts with Customers. 605 July 9, 2015, No. 2014 09 December 15, 2016 December 15, 2017. not no In January 2017, 2017 04, Intangibles – Goodwill and Other (Topic 350 ): Simplifying the Test for Goodwill Impairment 2 2, December 15, 2019, January 1, 2017 not In June 2018, 2018 07, Improvements to Nonemployee Share-Based Payment Accounting December 15, 2018. 2018 07 January 1, 2019 not In July 2019, 2019 07, 2019 07 2019 07 not Uncertainties The Company has realized a cumulative net loss of $5,443,294 June 2, 2015) December 31, 2019, $507,983, 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.

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, 2019 201 8 Options 21,716,557 216,557 Warrants 570,000 1,061 Series A convertible preferred stock 115,000 115,000 Convertible debt 13,11,457 289,804,783 Total potentially dilutive shares 35,523,014 290,137,401

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. 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 not
