Description	Quantum dots (QDs), semiconductor nanocrystals small enough to exhibit size-dependent properties, have generated tremendous interest due to their unique optical properties, including broad excitation spectra, narrow, tuneable and symmetric emission spectra covering the wide range of spectra from visible to infrared, excellent photostability and large quantum yield. In this study, electrochemical behaviour of quantum dots was studied using differential pulse voltammetry and cyclic voltammetry. Based on the results obtained, we suggested novel and easy-to-use method how to quantify quantum dots and how to evaluate the ratio of their degradation, which is very important for further using of these particles.
