Founded in 1991 by the inventors of Electric Cell-substrate Impedance Sensing, Applied BioPhysics manufactures ECIS® instruments and electrode arrays that monitor living cells in tissue culture in real time. Based in Troy, New York, the company applies biophysical research to cell research and drug discovery, with 95 percent of its products made at its U.S. facility. Its systems give researchers a label-free way to study cell behavior while maintaining active connections with the academic community that helped shape the technology.
