GOLD NANOPARTICLE AGGREGATION-INDUCED QUANTITATIVE PHOTOTHERMAL BIOSENSING USING A THERMOMETER

摘要

A biosensing system configured to detect a target DNA and methods of detecting a target DNS are presented. The biosensing system comprises a biosensor comprising a suspension of a hybridization buffer containing dispersed gold nanoparticles, sodium chloride, and single-stranded DNA probes configured to undergo DNA hybridization with the target DNA.
