A colorimetric logic gate based on free gold nanoparticles and the coordination strategy between melamine and mercury ions
A colorimetric logic gate based on free gold nanoparticles is presented with melamine and Hg2+, as well as its colorimetric detection of Hg2+ with good selectivity and sensitivity.
Graphene carrier for magneto-controllable bioelectrocatalysis
A magnetically driven fuel-free graphene carrier loaded with redox-active cargo-ferrocene as an electron mediator is fabricated for magneto-controllable bioelectrocatalysis. The activation and deactivation of redox-active ...
