Aptamer–gold nanoparticle conjugates for the colorimetric detection of arboviruses and vector mosquito species

Abstract

PFU live Zika virus. These aptamer-gold nanoparticle conjugate diagnostics could one day prove to be useful as deployable nano-based biosensors that provide easy-to-read optical read outs through a straightforward red-to-blue colour change either within a diagnostic solution or atop a card/membrane-based biosensor.
