The Department of Defense, specifically the Department of the Army, is seeking contractors to develop Robust Sensing Chips and a High-Throughput Multiplex Biosensor Calibrator aimed at enhancing biological detection calibration capabilities for military applications. The primary objective is to create engineering prototypes that can accurately identify biological warfare agents using advanced laser-induced fluorescence technology, ensuring compliance with National Institute of Standards and Technology (NIST) standards. This initiative is critical for improving the U.S. military's biological defense capabilities, particularly in the context of the Joint Biological Point Detection System (JBPDS) and the Joint Biological Tactical Detection System (JBTDS). Interested parties can reach out to Taven Graves at taven.l.graves.civ@army.mil or Martha C. White at martha.c.white8.civ@army.mil for further information, noting that this is a Sources Sought notice and not a request for proposals.
