摘要
Exposing oligodeoxynucleotide (ODN)-capped Au nanoparticles to a quartz crystal under shear oscillation resulted in the formation of a uniform monolayer containing these nanoparticles or multilayers with islands of the ODN-capped nanoparticles, which, in turn, improved the extent of DNA hybridization.
