Sensor and method for detecting predetermined chemical species in solution

摘要: A chemical sensor for measuring a change in the mass relating to interaction of surface with solution comprises crystal detector oscillator capable providing measurement signal based upon resonant frequency oscillator. The has first side directly contacting solution, and second isolated from solution. electrode is integral side, having an inner outer perimeter defining portion which exterior interior electrode. side. may be employed detect concentration predetermined species by adsorbing species-specific complementary material such as antibody onto active sites thereafter species-containing also used measure degradation coating applied thereof.
