Confined gold nanoparticles enhance the detection of small molecules in label-free impedance aptasensors

Mostrar todas las versiones(3)

A controlled architecture of nanoelectrodes, of a similar size to small molecule-binding aptamers, is synthesized inside nanoporous alumina. Gold nanoparticles with a controlled size (about 2 nm) are electrogenerated in the alumina cavities, showing a fast electron transfer process toward ferrocyani...
