摘要：

Focuses on a study which described the scanometric DNA array, oligonucleotide-modified gold nanoparticle probes and a conventional flatbed scanner, for analyzing combinational DNA arrays. How the gold nanoparticles modified with oligonucleotides were used; How to facilitate visualization of nanoparticle labels hybridized to the array surface; Hybridization properties of oligonucleotide-functionalized nanoparticles.
