Quantum Chemical Characterization and Design of Quantum Dots for Sensing Applications
Aleksandra Foerster, Nicholas A. Besley
Abstract
QDs have the potential to act as fluorescent markers that could distinguish between the oxidized and reduced forms of dopamine, where the fluorescence would be quenched for the oxidized form. The work contributes to a better understanding of the optical and electronic behavior of QD-based sensors and illustrates how quantum chemical calculations can be used to inform the design of QDs for specific fluorescent sensing applications.
