The Human Genome Project revealed DNA variations that are involved in the pathogenesis of disease, disease predisposition and metabolism of drugs. Detection and characterization of these polymorphisms (genotyping) is an important goal of biomedical research, because it is related to the discovery of novel prognostic or diagnostic markers and development of individualized medicine. The present dissertation focuses on the development of novel methods for genotyping single nucleotide polymorphisms (SNPs). The methods are rapid, simple, reliable and of low cost. These methods are based: (a) on a dry reagent DNA biosensor, which enables visual detection of allele specific products, without instrumentation, and (b) on bioluminometric assay of allele specific products in microtiter wells. Detection by the DNA biosensor exploits the unique optical properties of gold nanoparticles as reporters whereas the bioluminometric method is based on an enzyme (alkaline phosphatase) reporter, combined wit ...
