This paper reports a novel DNA hybridization detection method using gold-streptavidin conjugates as a reporter, the silver enhancement reaction to magnify the detection signal, a commercial LCR meter to detect the hybridization signal. The relationships between sample concentration and detection signal are discussed and the detection limit for the DNA sample is 0.825 ng/mL. Moreover, the probe specific tests are discussed for different species of bacteria, for same species but different strains, and for same genus but different species.
