Description/Abstract
An optical diffraction based sensor has been developed for the detection of DNA-gold nanoparticle hybrids. Silicon substrates were patterned with oligonucleotide sequences in the form of a one-dimensional diffraction grating. Complementary sequences are detected by hybridisation with an oligonucleotide functionalised gold nanoparticle label. Detection of the gold nanoparticles is achieved by examining the diffraction efficiency of the diffraction gratings formed by laser illumination.
