Abstract:
A matrix biochip sensing system, comprising:a matrix light source comprising a plurality of light generating spots arranged in a matrix wherein each light generating spot generates a light independently; a biochip clamping element, positioned in the downstream position relative to said matrix light source to position a biochip comprising a matrix distribution, wherein each spot of said matrix distribution of said biochip is spatially corresponding to one light generating spot of said matrix light source; an optical sensor to sense light power of respective spots of said matrix distribution of said biochip, after being actuated by light generated by said light generating spot of said matrix light source; and an optical signal processing and control module to control light generating from respective light generating spots of said matrix light source whereby only one light generating spot generates light during one working cycle, and to record time of light generation and light power as sensed by said optical sensor.
