Abstract:
Objective To develop a portable analyzer which can rapidly detect antigen of type B hepatitis,antibody of HIV and H5N1 in blood samples.Methods The micro-processor of STC89C52 was adopted as the controlling core in the system.Based on an embedded technology,the analyzer can rapidly detect the antigen of type B hepatitis,antibody of HIV and H5N1 by processing the synchronic frequency of quartz crystal micro-array and by sensitivity of quality on the surface of quartz crystal with special identification between antibody and antigen.Results The system has the advantages of high sensitivity,better sample-specific characteristics,convenient portability and multi-parameter simultaneous detection.Conclusion The piezoelectric analyzer exceeds the traditional reagent method and serves for institution of scientific research and hospital widely.
