Abstract
In this work new biosensor system based on ion selectivity field effect transistor is proposed. This sensor is used to detect the acute phase protein – C-reactive protein (CRP). There is the working principle and the results of experiments using a diluted standard samples kit. A working volume is only 20 μl and a range of working concentrations of CRB in the solution for the proposed sensor is 0.2 mg/L–25 mg/L have been established. For the proposed sensor, the sensitivity is 91.25 mV/(mg/L), and the measurement time is just about 1 min. In addition to experimental data, further stages of research and ISFET biosensor's improvement are proposed.
