Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Note 1 – Nature of Operations and Basis of Presentation SeqLL Inc. was incorporated as a Delaware corporation on April 3, 2014. On April 8, 2014, SeqLL Inc. acquired a 100% ownership interest in SeqLL, LLC (“Subsidiary”), a domestic limited liability company formed on March 11, 2013 in the State of Massachusetts. SeqLL Inc. is a holding company of the Subsidiary (together the “Company” or “SeqLL”) and is a life sciences company focused on the development and application of innovative genetic analysis technologies and the monetization of these technologies and related intellectual property. The Subsidiary owns technology to enable the analysis of large volumes of genetic material by directly sequencing single molecules of DNA or RNA. The Subsidiary’s principal office is located in Billerica, Massachusetts. Initial Public Offering On August 31, 2021, the Company completed its initial public offering (“IPO”) whereby it sold 3,060,000 units, each unit consisting of one share of the Company’s common stock and a warrant to purchase one share of common stock at an exercise price of $4.25 per share (the “Warrants”), at a price to the public of $4.25 per unit. The gross proceeds from the IPO were approximately $13 million and were offset by $3.2 million in offering costs, of which $1.6 million was paid in cash and $1.6 million was issued in warrants to Maxim Group LLC (“Underwriter”) (see Note 10). In connection with the IPO, all of the outstanding shares of the Company’s convertible preferred stock automatically converted into 3,130,622 shares of common stock (see Note 9). Additionally, the outstanding convertible notes converted into 641,895 shares of common stock (see Note 8). Pursuant to the Underwriting Agreement, the Company granted the Underwriter a 45-day option to purchase up to 459,000 additional shares of common stock, and/or 459,000 additional Warrants, to cover over-allotments in connection with the Offering. The Underwriter partially exercised this option and purchased 459,000 Warrants on August 31, 2021, at $0.01 per Warrant. On September 29, 2021, the Company issued 189,000 shares of common stock to the underwriters at a price of $4.24 per share from the exercise of the overallotment option, raising the net proceeds of approximately $730,000, net of offering costs. On August 31, 2021, and September 29, 2021, the Company also issued to the Underwriter warrants to purchase up to a total of 162,450 shares of common stock at an exercise price of $4.675 per share (“Underwriter Warrants”) (Note 10). Notice from the Nasdaq Stock Market On June 21, 2022, SeqLL received notice from The Nasdaq Stock Market (“Nasdaq”) indicating that, because the closing bid price for its common stock has fallen below $1.00 per share for 30 consecutive business days, the Company no longer complies with the $1.00 minimum bid price requirement for continued listing. Initially, the Company had approximately 180 days to regain its compliance with the Nasdaq. On December 20, 2022, the Company filed with, and received notice from, the Nasdaq that the Company is eligible for an additional 180 day period, in other words, until June 19, 2023, to regain its Nasdaq compliance. The notification of noncompliance has no immediate effect on the listing or trading of the Company’s common stock or its warrants to purchase common stock under the symbols “SQL” and “SQLLW,” respectively. To regain compliance, the closing bid price of the Company’s common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days. If the Company does not regain compliance by June 19, 2023, and it has been determined that the Company will not be able to cure the deficiency, Nasdaq will provide notice that the Company’s common stock will be subject to delisting. The Company would have the right to appeal a determination to delist its common stock, and the common stock would remain listed on The Nasdaq Capital Market until the completion of the appeal process. Risks and Uncertainties The Company is subject to a number of risks similar to other companies in its industries, including rapid technological change, competition from larger pharmaceutical and biotechnology companies and dependence on key personnel. Results of operations may be adversely affected by various factors that could cause economic uncertainty and volatility in the financial markets, many of which are beyond the Company’s control. The Company’s business could be impacted by, among other things, downturns in the financial markets or in economic conditions, inflation, increases in interest rates, the ongoing effects of the COVID-19 pandemic, including resurgences and the emergence of new variants, and geopolitical instability, such as the military conflict in the Ukraine. The Company cannot at this time fully predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact the Company’s business. Basis of Presentation The accompanying consolidated financial statements include the accounts of SeqLL Inc. and its wholly-owned subsidiary, SeqLL, LLC. All intercompany accounts and transactions have been eliminated in consolidation.
