title: Colorimetric SNP analysis using oligonucleotide-modified nanoparticles.
abstract: A point mutation in the p53 gene has been detected by means of fluorescence microscopy and fluorescent resonance energy transfer (FRET) through sequence selective aggregation of DNA-modified nanoparticles, in which fluorescent dyes were impregnated.
