Research On Pocket Multi-channel Apoptosis Detecting System

ISFET is based on MOSFET structure and used to measure biochemical parameter. The multi-parameter biochemical measure system uses ISFETs which have different sensitive area to realize multi-parameter detection. It has high sensitivity and high stability. The system can detect biochemical parameter through little sample rapidly.This paper describes the principle of biochemical measure system and the rules of designing pocket instrument. A multi-parameter biochemical measure system used to detect TNF-related Apoptosis-induced Ligand(TRAIL) is introduced. The system consists 8 sensors, a DSP or MCU, a circuit for selection and transform, a A/D convertor, a power supply module, a monitor software on PC, a printer, a display and a keyboard. The whole process of measure is monitored by PC. All the experiment data can be displayed by graphics and saved in database.A multi-parameter biochemical measure system we developed to detect TNF-related Apoptosis-induced Ligand(TRAIL) has been used in Affiliated Hospital of ChangZhi Medical College and Basal Medical College of Sun Yat-sen University practically. The detect result was accord with present detect method. We have completed the "863" project "The research for practical use of TNF-related Apoptosis-induced Ligand measure system" and developed a A multi-parameter biochemical measure system that could be used practically. The system is very promising.
