Abstract

The detection of specific sequences of DNA bases in a single strand can be achieved by hybridization of a known sequence of synthetic DNA. Due to the low concentrations usually used, a fluorescent label is required to detect the probe. Surface enhanced resonance Raman scattering (SERRS) also has the required sensitivity and provides a specific set of signals that are more applicable to discrimination of a number of probes without separation. A reliable SERRS method is reported here using two probes specifically designed for SERRS. It was possible to detect a 2 x 10(-12)M solution of labeled DNA, which illustrated the sensitive nature of SERRS for DNA analysis.
