Nanoparticles in aqueous environment: electrochemical, nanogravimetric, STM, AFM and DLS studies

Electrochemistry due to its simplicity and prompt response, low cost and relatively high sensitivity and selectivity, is a good alternative analytical technique for characterization and quantification of different nanoparticles (NPs) (1, 2). Voltammetric measurements in combination with electrochemical nanogravimetric measurements (EQCM) and atomic force and scanning tunneling microscopy (AFM, STM) on different electrode surfaces (Hg, Au) give more details and information related to attachment, adsorption, deposition and interaction between selected NPs and functionalized electrode. Particle deposition mechanisms are studied in relation to variations of particle charge, particle size and applied electrode potential, all with the aim to improve and develop new analytical methods for fast, selective, qualitative and quantitative NPs characterization and detection in natural waters.
