Optical Readout of Gold Nanoparticle-Based DNA Microarrays without Silver Enhancement

We present a novel readout scheme for gold nanoparticle-based DNA microarrays relying on “Laser-Induced Scattering around a NanoAbsorber”. It provides direct counting of individual nanoparticles present on each array spot and stable signals, without any silver enhancement. Given the detection of nan...
