The Department of Defense (DoD) is seeking innovative solutions through the Small Business Innovation Research (SBIR) program to develop electrochemical detection methodologies for aerosolized chemical and biological threats. The objective is to create portable, reusable devices capable of rapid, sensitive, and specific detection of such threats, addressing current limitations in existing detection methods that are often slow, costly, and prone to false readings. This initiative is critical for enhancing force protection and operational awareness, with potential applications in law enforcement, homeland security, and public health sectors. Interested parties should note that the solicitation will open on April 23, 2025, and close on May 21, 2025, with further details available at the DoD SBIR/STTR website.
