Uncoated negatively charged silver nanoparticles: speeding up the electrochemical synthesis

A new electronic device has been assembled and employed to obtain a stable solution of spherical uncoated silver nanoparticles (SNPs) in only 10 min. Time of current inversion phase, number of electrodes and purification procedure have been optimized; different techniques as UV–vis spectroscopy, transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), dynamic laser light scattering (DLS) have been carried out...
