Fluorescence Sensing with Molecularly Imprinted Polymer-Capped Quantum Dots.

ABSTRACT

Procedures for the design of a fluorescence sensor based on molecularly imprinted polymer-capped quantum dots (MIP@QDs) together with the synthesis of quantum dots and MIP@QDS are described. Spherical and monodispersed nanoparticles are suitable for fluorescence sensing of an analyte such as pharmaceuticals and polycyclic aromatic hydrocarbons (PAHs). In addition, excellent optical properties, higher quantum yield, and photoluminescence efficiency as well as easy detection of emission spectra are distinctive advantages of quantum dots as fluorescence sensors. Optimization of different variables and analytical applications of the sensor are also presented, which are of value for fluorescence sensing.
