Schistosomiasis control remains to be an important and challenging task in the world. However, lack of quick, simple, sensitive and specific sero-diagnostic test is still a hurdle in the control practice. The commonly employed enzyme-linked immuno-sorbent assay (ELISA) relies on the native soluble egg antigen (SEA) that is limited in supply. Here we developed an electrochemical immunosensor arr...

Development of flow injection analysis (FIA) is reported for determination of total antioxidant capacity of alcoholic beverages (wines and spirits) by bienzymatically produced ABTS + and electrochemical detector using interdigitated gold electrode (IDE). The method is based on biamperometric measurements using ABTS jABTS redox couple. During the analysis, ABTS radical cation was bienzymatically...

Chitosan membrane with glutathione reductase and sulfhydryl oxidase (SOX) was subsequently integrated onto the surface of spectrographic graphite rods for obtaining a glutathione biosensor. The working principle was based on the monitoring of O(2) consumption that correlates the concentration of glutathione during the enzymatic reaction. A linear relationship between sensor response and concent...

In this paper we report the fabrication, design and testing of an uncooled infrared imager based on an active pixel heat balancing technique. The imager is fabricated using a commercial CMOS process plus a simple electrochemical etch stop releasing step. The basic active pixel detector structure consists of a simple cascode CMOS amplifier in which the PMOS devices are built inside a thermally-i...
