Abstract:

The aim of this oral presentation is to deeply investigate the structure and properties of electrochemically synthesised silver nanoparticles (AgNPs) through high-resolution techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), zeta potential measurements and matrix-assisted laser desorption/ ionization-time of flight mass spectrometry (MALDI-TOFMS). Strong brightness, tendency to generate nanoclusters containing an odd number of atoms and absence of the free silver ions in solution was observed. Our laboratory also highlighted that the chemical and physical properties of the AgNPs seemed to be related to their peculiar oxidative state as suggested by X-ray photoelectron spectroscopy (XPS) and X-ray powder diffraction (XRPD) analyses. Finally, the MTT assay tested the low cytotoxicity of the investigated AgNPs. For the first time, nanolcusters solutions with reproducible characteristics are used for investigating the primary effect responsible for cell death. Recent Publications 1.
