Foothold Labs Inc, a division of Valor Professional Solutions, develops an AI enabled electrochemical biosensor based rapid diagnostic platform for healthcare, water, agriculture, and food safety applications. The company's NanoRev technology uses an impedance based detection method which makes low levels of detection possible through direct engagement between bioreceptors and target antigens. This combines with machine learning software that enables their rapid diagnostic platform. Their primary product, NanoRev System, offers a portable and accurate rapid diagnostic system utilizing electrochemical biosensors to detect target bacterial or viral pathogens in saliva, urine, or blood serum.
