Abstract
En 中文
Using gold nanoclusters (AuNC), nano polytetrafluoroethylene (PTFE), and the two nanoparticles as the nanocarriers, methacrylic acid as the functional monomer, and pymetrozine (PT) as template molecule, the three surface molecularly imprinted polymer (SMIP) nanoprobes including AuNC@MIP, PTFE@MIP and (AuNC + PTFE)/2@MIP (C@MIP) were prepared. It was characterized by Transmission electron microscopy, X-ray photoelectron spectroscopy and molecular spectroscopy. The three SMIPs and the mixture of two probes (AuNC@MIP/2 + PTFE@MIP/2) exhibit strong catalysis on the nanosilver indication reaction of AgNO3-sodium lactate (SL) to form silver nanoparticles (AgNP) with resonance Rayleigh scattering (RRS) effect at 350 nm. Under the ultrasonic heated conditions, the two nanocatalytic probe system exhibits superstrong catalysis due to coupling with the electrons of triboelectric nanogenerator (TENG). In the catalytic analysis system, the RRS signal increased linearly with the PT concentration in the range of 0.1-1.75 nmol/L. This RRS method was applied to determine PT in food samples, with relative standard deviation of 1.6-8.6 % and recovery of 92.42-109.3 %.
