A novel detection platform for parallel monitoring of DNA hybridization with high sensitivity and specificity

摘要

We developed a high-sensitive platform to monior multiple hybridization events in real time. By creating a microoptical array in a polymeric chip, the system combine the excellent discriminative power of supercritical angle fluorescence (SAF) microscopy with high-throughput capabilities of microarrays. The micro-optical array is easy to fabricate, and exhibits significantly improved analytical performance. It has a potential to become a basic tool for applications such as gene expression or single nucleotide polymorphism (SNP) detection.
