N-6 methylation of adenine destabilises duplex DNA and this can increase the proportion of DNA that dissociates into single strands. We have investigated utilising this property to measure the DNA adenine methyltransferase-catalyzed conversion of hemimethylated to fully methylated DNA through

A novel fluorescent sensor for the detection of Hg(2+) in aqueous media was developed. The method takes advantages of the highly selective thymine-Hg(2+)-thymine coordination and the sensitive "signal-on" structure-switching molecular beacon.

Sensitive and specific enzyme-linked immunosorbent assays (ELISAs) were developed for the detection of two illegal synthetic dyes: Methyl Yellow (MY) and Rhodamine B (RB) in food. Polyclonal antibodies were raised against synthesised immunogens and employed in unique direct disequilibrium ELISAs.
