A MICROARRAY COMPRISING A SUBSTRATE FORMED WITH TWO DIMENSIONAL GRATING AND METHOD FOR DETECTING A TARGET MOLECULE BY USING THE SAME

摘要

A microarray including a substrate having a first diffraction grating and a second diffraction grating formed perpendicularly to each other is provided. Also, a method of detecting a target molecule in a sample is provided. The method includes: placing a sample containing a labelled target molecule on a diffraction grating on the above microarray to react with a probe molecule immobilized on the diffraction grating; irradiating a first electromagnetic wave to a product of a reaction between the target molecule and the probe molecule; and detecting a second electromagnetic wave emitted from the labelled probe molecule.
