Original Abstract

New type of quantum dots (QDs) are synthesized using various types of passivators, thus the question of their stability and way of storage is still opened not only due to characterization but also due to their wide application (chemistry, chemical biology and biomedicine, gene technology, tumour biology investigation, and fluorescent labelling). In our study, we are interested in the electrochemical changes as a result of aging and storage. We employed a series of aqueous solutions of QDs from various materials with different capping agents (PbS and CuS capped with 3-mercaptopropionic acid, CdS and CdTe capped with mercaptosuccinic acid) and the changes in typical peaks for metals and passivators (acids) were detected by difference pulse voltammetry, after 28 days storage in daylight (25oC) and dark (4oC). Anodic stripping difference pulse voltammetry offers simple and inexpensive approach for monitoring of nanoscaled products behaviour in time, based on evaluation of both - metal and passivator peak.

Keywords
