. The review gives an overview of cyclic voltammetry measurements performed on CdSe nanocrystals (so called Quantum Dots). Data of relevant publications is gathered and newly interpreted to give complete insights in charge transfer processes at QD surfaces. In specific, it is focused on the size-dependent electronic properties (Quantum-Size-Effect), the characterisation of surface defects, and the...
. The application of silica coated quantum dots (QDs@SiO2) in glucose detection in combination with glucose oxidase is reported. The high specific surface area of such particles can be exploited to immobilise a greater amount of the enzyme on a modified electrode. In addition to this electrochemical method, we report here an indirect optical technique based on the photoluminescence quenching of QDs...
