| Comparability of Prior Year Financial Data, Policy [Policy Text Block] |
Prior Period Presentation — The Company allocated the proceeds of the November 2016 Underwritten Offering between the Series A Preferred Stock and the Series C Warrants based on fair value and correctly recorded the Series A Preferred Stock as equity, however the embedded beneficial conversion feature (BCF) associated with the Series A Preferred Stock was not properly considered. ASC 470-20 required the Company to reflect in its presentation of net loss attributable to common stockholders a BCF of approximately $3.2 million. Additionally, shares used in computing basic and diluted net loss per common share were overstated by approximately 0.2 million shares. The net effect was to increase net loss attributable to common shareholders per share by ($0.78). These had no effect on cash, cash flows or total shareholders’ equity during 2016 and had no effect on cash, cash flows, net income or total stockholders’ equity for any subsequent periods. After considering the quantitative and qualitative effects to the 2016 annual financial statements, as well as the quarterly period financial statements within 2016, in the opinion of management, it is not material to assessing the financial condition or operations of the Company. |

| Consolidation, Policy [Policy Text Block] |
Principles of Consolidation — The consolidated financial statements include the accounts of the Company and the accounts of its wholly-owned subsidiary. All inter-company accounts and transactions have been eliminated in consolidation. |
|
| Use of Estimates, Policy [Policy Text Block] |
Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and judgments that may affect the reported amounts of assets, liabilities, revenue and expenses and disclosure of contingent assets and liabilities. On an on-going basis, management evaluates its estimates including those related to unbilled vendor amounts, share-based compensation and derivative liability valuation. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from those estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known. |
|
| Cash and Cash Equivalents, Policy [Policy Text Block] |
Cash and Cash Equivalents — All short-term investments purchased with original maturities of three months or less are considered to be cash equivalents. |
|
| Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block] |
Restricted Cash — The Company accounts for cash and claims to cash that are committed for other than current operations as restricted cash. Restricted cash at December 31, 2017 and 2016 consists of a certificate of deposit of $55,000 required under the Company’s lease agreement for its Madison, Wisconsin facility (see Note 12). |
|
| Property, Plant and Equipment, Policy [Policy Text Block] |
Fixed Assets — Property and equipment are stated at cost. Depreciation on property and equipment is provided using the straight-line method over the estimated useful lives of the assets (3 to 10 years). Due to the significant value of leasehold improvements purchased during the initial 3-year lease term and the economic penalty for not extending the building lease, leasehold improvements are depreciated over 17 years (their estimated useful life), which represents the full term of the lease, including all extensions. With the exception of goodwill, our only long-lived assets are property and equipment. The Company periodically evaluates long-lived assets for potential impairment. Whenever events or circumstances change, an assessment is made as to whether there has been impairment to the value of long-lived assets by determining whether projected undiscounted cash flows generated by the applicable asset exceed its net book value as of the assessment date (see Note 5). In December 2017, the Company concluded that the manufacturing processes would be transferred to a third party. As part of the transfer, the Company also began the process of de-commissioning the manufacturing facility. In connection with the de-commissioning, the Company determined that certain research and development assets will no longer be used by the Company and had materially ceased being used by December 31, 2017. As a result, the Company reassessed the estimated useful life of the research and development assets and concluded they should be accelerated beginning on December 1, 2017 through December 31, 2017 (one month remaining life). The Company also reassessed the estimated useful life of the leasehold improvements and concluded that they should be accelerated beginning on December 1, 2017 through December 31, 2017 (one month remaining life). These reassessments of the estimated useful lives have been accounted for as changes in an estimate. The effect of these changes in estimates was to increase 2017 depreciation expense by approximately $1,176,000, increase 2017 net loss by approximately $1,176,000, and increase 2017 basic and diluted net loss attributable to common stockholders per share by $0.08. |
|
| Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block] |
Goodwill — Intangible assets at December 31, 2017 and 2016 consist of goodwill. Goodwill is not amortized, but is required to be evaluated for impairment annually or whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. The Company evaluates goodwill for impairment annually in the fourth fiscal quarter and additionally on an interim basis if an event occurs or there is a change in circumstances, such as a significant decline in the Company’s stock price or a material adverse change in the business climate, which would more likely than not reduce the fair value of the reporting unit below its carrying amount (see Note 4). In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Simplifying the Test for Goodwill. The standard streamlines the methodology for calculating whether goodwill is impaired based upon whether the carrying amount of goodwill exceeds the reporting unit’s fair value. ASU 2017-04 applies to public business entities and those other entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill and is effective for annual and interim reporting periods beginning after December 15, 2019, with early adoption permitted. The Company does not expect that the adoption of this standard will have a material effect on its financial statements. |

| Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] |
Stock-Based Compensation — The Company uses the Black-Scholes option-pricing model to calculate the grant-date fair value of stock option awards. The resulting compensation expense, net of expected forfeitures, for awards that are not performance-based is recognized on a straight-line basis over the service period of the award, which is generally three to four years for stock options. For stock options with performance-based vesting provisions, recognition of compensation expense, net of expected forfeitures, commences if and when the achievement of the performance criteria is deemed probable. The compensation expense, net of expected forfeitures, for performance-based stock options is recognized over the relevant performance period. Non-employee stock-based compensation is accounted for in accordance with the guidance of FASB Accounting Standards Codification (“ASC”) Topic 505, Equity. As such, the Company recognizes expense based on the estimated fair value of options granted to non-employees over their vesting period, which is generally the period during which services are rendered and deemed completed by such non-employees. |
|
| Research and Development Expense, Policy [Policy Text Block] |
Research and Development — Research and development costs are expensed as incurred. To the extent that such costs are reimbursed by the federal government on a fixed price, best efforts basis and the federal government is the sole customer for such research and development, the funding is recognized as a reduction of research and development expenses. |
|
| Income Tax, Policy [Policy Text Block] |
Income Taxes — Income taxes are accounted for using the liability method of accounting. Under this method, deferred tax assets and liabilities are determined based on temporary differences between the financial statement basis and tax basis of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when it is more likely than not that some portion of the deferred tax assets will not be realized. Management has provided a full valuation allowance against the Company’s gross deferred tax asset. Tax positions taken or expected to be taken in the course of preparing tax returns are required to be evaluated to determine whether the tax positions are “more likely than not” to be sustained by the applicable tax authority. Tax positions deemed not to meet a more-likely-than-not threshold would be recorded as tax expense in the current year. There were no uncertain tax positions that require accrual to or disclosure in the financial statements as of December 31, 2017 and 2016. |
|
| Fair Value of Financial Instruments, Policy [Policy Text Block] |
Fair Value of Financial Instruments — The guidance under FASB ASC Topic 825, Financial Instruments, requires disclosure of the fair value of certain financial instruments. Financial instruments in the accompanying financial statements consist of cash equivalents, accounts payable and long-term obligations. The carrying amount of cash equivalents, and accounts payable approximate their fair value due to their short-term nature. The carrying value of long-term obligations, including the current portion, approximates fair value because the fixed interest rate approximates current market rates of interest available in the market. |
|
| Derivatives, Policy [Policy Text Block] |
Derivative Instruments — The Company generally does not use derivative instruments to hedge exposures to cash flow or market risks; however, certain warrants to purchase common stock that do not meet the requirements for classification as equity, in accordance with the Derivatives and Hedging Topic of the FASB ASC, are classified as liabilities. In such instances, net-cash settlement is assumed for financial reporting purposes, even when the terms of the underlying contracts do not provide for a net-cash settlement. These warrants are considered derivative instruments because the agreements contain a certain type of cash settlement feature, contain “down-round” provisions whereby the number of shares for which the warrants are exercisable, and/or the exercise price of the warrants are subject to change in the event of certain issuances of stock at prices below the then-effective exercise price of the warrants. The number of shares issuable under such warrants was 533,065 at December 31, 2017 and 2016, respectively. The primary underlying risk exposures pertaining to the warrants and their related fair value is the change in fair value of the underlying common stock, the market price of traded warrants, and estimated timing and probability of future financings. Such financial instruments are initially recorded at fair value with subsequent changes in fair value recorded as a component of gain or loss on derivatives on the consolidated statements of operations in each reporting period. If these instruments subsequently meet the requirements for equity classification, the Company reclassifies the fair value to equity. At December 31, 2017 and 2016, these warrants represented the only outstanding derivative instruments issued or held by the Company. |
|
| Concentration Risk, Credit Risk, Policy [Policy Text Block] |
Concentration of Credit Risk — Financial instruments that subject the Company to credit risk consist of cash and equivalents on deposit with financial institutions. The Company’s excess cash as of December 31, 2017 and 2016 is on deposit in interest-bearing transaction accounts with well-established financial institutions. At times, such amounts may exceed the FDIC insurance limits. As of December 31, 2017, uninsured cash balances totaled approximately $9,600,000. |
|
| Lessee, Leases [Policy Text Block] |
Leases — In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which supersedes FASB ASC Topic 840, Leases (Topic 840) and provides principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than twelve months regardless of classification. Leases with a term of twelve months or less will be accounted for similar to existing guidance for operating leases. The standard is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted upon issuance. The Company is currently evaluating the method of adoption and the impact of adopting ASU 2016-02 on its results of operations, cash flows and financial position. |
|
| New Accounting Pronouncements, Policy [Policy Text Block] |
Recent Accounting Pronouncements - In July 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815). The amendments in Part I of this Update change the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. The standard is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted upon issuance. The Company is currently evaluating the method of adoption and the impact of adopting ASU 2017-11 on its results of operations, cash flows and financial position. |
