Biorecognition-modulated ion fluxes through functionalized gold nanotubules as a novel label-free biosensing approach

Biorecognition-modulated ion fluxes through functionalized gold nanotubules as a novel label-free biosensing approach

A novel biosensing principle is presented, based on the potentiometric monitoring of an indicator ion such as Ca2+, whose zero-current flux through chemically modified nanochannels is altered by biorecognition events.
