The combination of advantages of using zeolites and gold nanoparticles were aimed to be used for the first time to improve the characteristic properties of ion selective field-effect transistor (ISFET)-based creatinine biosensors. The biosensors with covalently cross-linked creatinine deiminase using glutaraldehyde (GA) were used as a control group, and the effect of different types of zeolites...

The method of cleaning the ISFET structures after application a biological substance was developed. There are few references in literature to methods this type structure for applications, but they relatively complex and difficult automate. We decided use resources commonly available technological laboratories that could be easily automated, which would enable full potential transistors used. Du...

Design conslderatlons for the multiplexing of pH-sensitive ISFETs are studied and discussed Expernnental results with an ordinary multiplex clrcult show transients of the order of several seconds if the output voltage of the applied amplifier 1s required wlthm an accuracy of 0 5 mV (corresponding to 0 01 pH unit) These transients appear to result from thermal mstablllty of the ISFETs during swi...

The objective of this article is to summarize the available technologies for biosensing applications in COVID-19. divided into three parts, an introduction technologies, mainstream and a review biosensors presents history inventing technology, which refers ISFET. resonant biosensor with example MEMS. principle optical biosensor, thermal biosensor. In second part, main use techniques, it was dis...

Sensor drift is an inevitable measurement problem and is particularly significant in the long term. The common practice is to have an auto-calibration facility (including standard buffers or accurate integrated actuators) mounted on the monitoring system. However, this approach may not be feasible when the monitoring system is miniaturized to the size of a capsule. In this paper, we develop an ...
