Abstract:
Unmodified gold nanoparticles (GNPs) can be wrapped with long genomic single- and double-stranded DNA (ssDNA and dsDNA) molecules produced by asymmetric polymerase chain reaction (As-PCR). More importantly, the DNA-Au interaction can be utilized for colorimetric detection of a specific nucleic acid sequence in clinical samples.
