An aptamer-controlled Mn-Au nanozyme for H2O2-free and smartphone-assisted colorimetric detection of mercury ions
A novel Hg2+ sensing strategy has been developed based on a Mn-Au hybrid nanozyme with prominent oxidase-like activity and an aptamer-controlled catalytic switching mechanism. First, a Mn-Au hybrid nanozyme (MnAuNPs) with a distinctive “fried-egg-like” core–shell morphology was synthesized, which exhibited remarkable o...
