摘要：
(Graph Presented) All that scatters... A single-molecule detection technique, named resonance light-scattering correlation spectroscopy, has been developed based on the extremely strong resonance light scattering of gold nanoparticles. This technology was successfully used to determine the size of gold nanoparticles, and to rapidly detect solution-phase DNA hybridization. Complementary and single-base mismatch oligonucleotides could be distinguished within 5 min. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
