DNA templated self-assembly of gold nanoparticle clusters in the colorimetric detection of plant viral DNA using a gold nanoparticle conjugated bifunctional oligonucleotide probe

Abstract

The DNA templated self-assembly of gold nanoparticles clustered in different configurations (<italic>n</italic>n = 2<italic>–</italic>∞) was investigated in the colorimetric detection of ToLCNDV DNA using a gold nanoparticle conjugated bifunctional oligonucleotide probe.
