Optimization design of suspension biochip detection system

In this paper, we describe a new kind of micro fluidic channel used in suspension biochip detection system that is different from cytometry. The key indexes of the detection system are space resolution and sensitivity, which both depended on optical system and filtering system. At first, the key factors which have great effect to space resolution have been analyzed. Secondly the filtering system of suspension array is analyzed. At last the transmission ration curve of the filters used in our detection system has been tested in detail. The optimization design suspension biochip is also obtained.
