Enhanced Resonance Light Scattering from CdS Quantum Dot-CTMAB for the Determination of Estradiol Valerate

Abstract:

A method is developed to detect estradiol valerate which is based on the phenomenon that estradiol valerate can enhance the resonance light scattering intensity of CdS QD. Cetyl Trimethyl Ammonium Bromide (CTMAB) is added to sensitize this system. Under optimum conditions, the enhanced intensity of the system is in proportion to the concentration of estradiol valerate in the range of 5.0×10^-8 ~ 6.0×10^-7 gmL^-1. The detection limit is 1.2×10^-8 gmL^-1. It has advantages that simple, sensitivity and stable.
