Nanoparticle coding: size-based assays using atomic force microscopy.


Described herein is a novel strategy for the construction and interrogation of an assay platform based on (1) the size encoding of labeled nanoparticles; (2) the high imaging resolution of atomic force microscopy; and (3) evaporatively driven self-assembly of dense nanoparticle layers. This strategy employs two different sized nanoparticles that couple in… (More)
