Abstract
A biochip includes a liquid crystal panel having liquid crystal cells each corresponding to each sample on a substrate. The liquid crystal panel includes an upper polarization filter, an upper transparent electrode, an upper orientation film, a liquid crystal, a lower orientation film, a lower transparent electrode and a lower polarization filter in this order. By application of voltage to a desired liquid crystal cell, external light is selectively radiated onto the sample. Thus, it is possible to achieve downsizing, cost reduction and high-speed operation of a biochip reader.
Claims6
A biochip comprising:
- a substrate having a plurality of samples;
- and
- a liquid crystal panel disposed on a side of the substrate where the samples are not provided and composed of a plurality of liquid crystal cells, wherein
- the liquid crystal panel includes an upper polarization filter, an upper transparent electrode, an upper orientation film, a liquid crystal, a lower orientation film, a lower transparent electrode, and a lower polarization filter,
- each of the samples is disposed in correspondence with each of the liquid crystal cells, and
- external light is selectively radiated onto the samples by application of voltage to the liquid crystal cells.
A method of reading a biochip having a plurality of samples, comprising the steps of:
- radiating light from a light source unit onto the samples;
- and
- receiving light generated from the samples, wherein
- light from the light source unit is radiated onto a desired sample by applying voltage selectively to liquid crystal cells corresponding to each of the samples.
