LIGHT ADDRESSING BIOSENSOR CHIP AND METHOD OF DRIVING THE SAME
First Claim
1. A biosensor chip comprising:
- a plurality of biosensor cells having;
photoelectric elements arranged in a matrix, and selectively turned on to generate a reference electric signal by addressing of external light; and
biosensors receiving the reference electric signal, and generating and outputting a sensed signal caused by a reaction between probe molecules and target molecules on a basis of the reference electric signal;
at least one sensing line simultaneously connected with the plurality of biosensor cells, and transmitting the sensed signal from one selected from the biosensor cells; and
output terminal receiving the sensed signal from the sensing line, and outputting the sensed signal to an external reader.

Abstract
Provided is a biosensor chip. The biosensor chip includes a plurality of biosensor cells that are arranged in a matrix and selectively generate and output a sensed signal by addressing of external light, at least one sensing line that is simultaneously connected with the plurality of biosensor cells and transmits the sensed signal from one selected from the biosensor cells, and an output terminal that receives the sensed signal from the sensing line and outputs the sensed signal to an external reader. Thus, the biosensor cells are set in array in the biosensor chip without a separate driving unit, so that a process of manufacturing the biosensor chip is simplified. The biosensor cell to be sensed is selectively addressed through the external light, so that it is possible to reduce a price of the biosensor chip used as a disposable chip.
