Kras gene codon 12 mutation detection enabled by gold nanoparticles conducted in a nanobioarray chip.

Abstract excerpt

This study employs a nanobioarray (NBA) chip for multiple biodetection of single base pair mutations at the Kras gene codon 12. To distinguish between the mutant and wild-type target DNAs, current bioarray methods use high-temperature hybridization of the targets to the allele-specific probes. However, these techniques need prior temperature optimization and become harder to implement in the case of the detection...
