Sarissa is developing a range of minimally invasive, microelectrode electrochemical sensors for the measurement of the purines and other neurochemicals, as indicators of neurological activity / disorders and has a product design platform that offers exquisite sensitivity, coupled with a broad linear activity range and high levels of accuracy and reproducibility. These biosensors are designed for in vitro and in vivo studies for research and diagnostic applications.

Crucial to the Sarissa's highly differentiated technology are the unique methods by which active enzyme-based layers are deposited onto the surface of the sensor. In the case of the ATP sensor (sarissaprobe®-ATP) the enzyme matrix includes glycerol kinase and glycerol-3-phosphate oxidase, deposited onto the surface of a Pt/Ir microelectrode.
