Aptamer Functionalized Micro/Nano-Nanoparticles to Recognize and Purify Pollutants

摘要

Trace emerging pollutants,such as antibiotics,polycyclic musks,toxins and viruses,have attracted people's intensive attentions.Given the trace (ppb or less) contaminations,sensitive methodologies to accurately measure the concentrations become emergent.To solve this problem,aptamer as a novel tool to recognize trace antibiotics,toxins and viruses.Aptamers as smart molecules can specifically recognize targets.Our research revealed that aptamer-based column can capture ng/L antibiotics in real drinking water.Moreover,the interactions of aptamer with pollutants were divided into three steps by chemical kinetics and thermodynamics.This is a
