We report a sensitive nanosensor based on a micro-fluidic chip and nanoparticles to detect low concentrations of DNA. The emission of CdSe/ZnS-QDs linked with single strand DNAs was quenched by gold nanoparticles linked with the complementary sequences after hybridization. Sensitively detected signal of DNA was obtained from a 100 mu m capillary.
