Abstract :
In this report, a handheld luminescence system based on complementary metal oxide semiconductor (CMOS) was constructed. The system composed of two major parts - a CMOS photodiodes array integrated chip (IC) and a 8051 microprocessor based voltage monitor. The handheld device showed great performance to quantify the biological luminescence, either in Horse-radish-peroxidase (HRP)/luminol/H2O2 reaction system or in HRP/glucose oxidase (GOD)/glucose couple enzyme reaction system; and also showed great capacity for personalized healthcare device.
