Gold nanoparticle aggregation-based highly sensitive DNA detection using atomic force microscopy
The potential ability of atomic force microscopy (AFM) as a quantitative bioanalysis tool is demonstrated by using gold nanoparticles as a size enhancer in a DNA hybridization reaction. Two sets of probe DNA w...
