Aptamer-mediated charge neutralization and aggregation of gold nanorods for fast visual monitoring of di(2-ethylhexyl) phthalate in foods and its release from PET containers.
Di(2-ethylhexyl) phthalate (DEHP) is an emerging endocrine-disrupting contaminant, and its rapid monitoring in food is critically important. We developed an aptamer-induced charge neutralization and aggregation of gold nanorods (AuNRs) strategy for facile detection of DEHP. The negatively charged aptamers were adsorbed...
