Preparation and comparison fluorescence sensor based on molecularly imprinted polymers carbon dots and molecularly imprinted polymers polymer dots for detection of acetamiprid

This study defined the design, development and Comparison of molecularly imprinted polymers of carbon dots (CDs) and polymer dots (PDs) for measure acetamiprid. PDs were prepared by a one-step aqueous synthetic way from ascorbic acid and diethylenetriamine at room temperature. That also CDs were prepared by hydrothermal method at 180 °C. These particles are characterized by means such as FE-SEM, FTIR, DLS, XRD, UV/Vis and fluorescence that quantum yield of PDs 47% and CDs 8%. At the next step, a thin padding of silica was covered, by reverse microemulsion Method, on the Outer environment of PDs and CDs. at the end, molecularly imprinted polymer inside it PDs and CDs were obtained. Other variables affecting the fluorescence peaking were optimized by design expert software. The results illustrate that the considered method for PDs had wide dynamic range 0.08-101 nmol L−1, good accuracy and detection limit 0.024 nmol L−1, also CDs had Thin dynamic range 0.12-2.19 nmol L−1 and detection limit 0.031 nmol L−1. The response of the optical sensor on usual specimens in water and Fruitage was considered. The consequence certified the well selectivity of the sensor for the evaluation of acetamiprid.
