The self-assembly of DNA block-copolymers and nanoparticles yields hybrid nanostructures with useful properties of incorporated nanoparticles and a high density DNA layer on the exterior. Remarkably, they exhibit drastically enhanced binding capability to complementary DNA even at very low salt concentrations where isolated DNA strands do not form duplex structure. This extraordinary binding capability along with the high selectivity allows for efficient duplex DNA detection.
