A simple AuNPs-based colorimetric aptasensor for chlorpyrifos detection
文献摘要：
In this work,a simple gold nanoparticles(AuNPs)based colorimetric biosensor was developed for chlor-pyrifos(Chl)detection using an aptamer as the capture probe.The Chl-aptamer with low dissociation constant(Kd)of 58.59±6.08 nmol/L was selected by ssDNA library immobilized systematic evolution of ligands by enrichment(SELEX).In the absence of Chl,the Chl-aptamer acted as the stabilizer for AuNPs in salt solution.In the presence of Chl,the highly specific Chl-aptamer bound with Chl targets immediately,thus a self-aggregation of AuNPs induced by salt was displayed.The fabricated colorimetric aptasensor exhibited an excellent sensitivity for Chl detection with the LOD as low as 14.46 nmol/L.In addition,the aptasensor was applied to test Chl in tap water,cucumber and cabbage samples,the excellent recoveries with acceptable RSD values below 5％demonstrated that the method can be considered as a promising tool for simple,rapid Chl detection.
