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

ABSTRACT: The real-time, colorimetric detection of analytes via aptamer-gold nanoparticle technology has proven to be an important, emerging technique within the medical field. Of global health importance, the ability to detect vector mosquito species, such as the Aedes (Ae.) aegypti mosquito, and transmitted arboviruses, such as Zika virus, is paramount to mosquito control and surveillance efforts. Herein, we describe the detection of Ae. aegypti salivary protein for vector identification and the detection of Zika virus to assess mosquito infection status by aptamer-gold nanoparticle conjugates. Key to optimization of these diagnostics were gold nanoparticle capping agents and aptamer degree of labelling (i.e., the amount of aptamers per gold nanoparticle).
