摘要：
A novel wireless magnetoelastic sensor (WMS) strategy for Hg2+ assay was proposed using a specific aptamer probe and graphene oxide (GO) as an adsorbent. The introduction of Hg2+ results in the release of CDNA-biotin. This one can be adsorbed to the surface of GO that was immobilized on the WMS along with a decrease of the resonance frequency of the sensor. A biotin-streptavidin (SA)-gold nanoparticles( AuNPs) system designed in this work was used for amplifying response signal of the sensor. The signal intensity linearly correlated with Hg2+ concentration ranging from 2.80 to 88.9 nM with a d...
