"Turn on" and label-free core−shell Ag@SiO(2) nanoparticles-based metal-enhanced fluorescent (MEF) aptasensor for Hg(2+)
A turn on and label-free fluorescent apasensor for Hg(2+) with high sensitivity and selectivity has been demonstrated in this report. Firstly, core−shell Ag@SiO(2) nanoparticles (NPs) were synthetized as a Metal-Enhanced Fluorescent (MEF) substrate, T-rich DNA aptamers were immobilized on the surfac...
