Paper Abstract

We adapted the nanoparticle-labeling technique from microscopical applications for DNA-chip detection. Nanoparticles can be detected by simple optical means, and exhibit a high stability. So alternative optical readout devices can be applied for the detection of specific DNA- binding on microstructured spots of complementary, surface- immobilized capture DNA. Several devices were tested, and the binding of gold-labeled DNA to complementary and non- complementary sequences was investigated using optical detection of the gold-labeled substrates before and after silver enhancement.
