Abstract
The present invention provides a biochip reader for reading with a detector the fluorescence image information from genes to which fluorescent substances are stuck and which are poured into biochip cells, by emitting coherent light beams such as laser light onto the cells as excitation light. The present invention aims to achieve a biochip reader that is small, cheap, and highly durable.
Claims4
A biochip reader comprising:
- a plurality of microlenses;
- a light source irradiating an excitation light to a plurality of cells of a biochip respectively via said plurality of microlenses;
- and
- a detector reading fluorescence image information from genes attached with fluorescent substances poured into said plurality of cells,
- wherein said light source is configured to generate the excitation light composed of a part of strong light intensity and another part of weak light intensity, and
- wherein on said biochip, genes of each cell are arranged so that genes are expressed less at the strong light intensity part and are expressed more at the weak light intensity part.
