Visual detection of single-nucleotide polymorphisms and DNA methyltransferase based on cation-exchange of CuS nanoparticles and click chemistry of functionalized gold nanoparticles†
Abstract
A novel biosensor was developed based on the cation-exchange of CuS nanoparticles (NPs) and Cu(I)-based click chemistry of functionalized gold nanoparticles (AuNPs). As a proof-of-principle, novel applications of this method as a versatile biosensor for single-nucleotide polymorphisms (SNPs) and DNA methyltransferase (MTase) were presented.
