H(+)-ISFET Type Penicillinase Sensor

Abstract

We took an SOS type H + - ISFET and pentyl dialdehyde connective bovine blood serum protein penicillinase membrane set and synthesized a single transistor output type penicillinase-H+-ISFET sensor probe (below simply designated penicillinase FET). In conjunction with this, it was used to measure the amount of penicillin contained in solutions. Ion sensitive field effect transistors as well as the biologically sensitive field effect transistors which have been developed on this basis, are a new type of microsemiconductor chemistry instrument which has been developed in recent years. They compare ion selection electrodes and enzyme electrodes to each other. They possess small volumes. The reactions are fast. Their output resistance is low and other similar special characteristics. They have drawn attention from relevent fields inside China and outside.
