In the present paper, we report the generation of silver nanoparticles by in situ photoreduction of the silver salt into an organic matrix based on vinyl acetate (VAc), p-acryloyloxybenzaldehyde (AcrBzA), N-methacryloyloxyethyl-N’-fluoresceinyl urea (MA-Fl) and/or trietoxysilylpropyl carbamoyloxyethyl methacrylate (TCM) and phenyl-bis(2,4,6-trimethylbenzoyl) phosphine oxide (Irgacure 819) as photoinitiator. The formation of the nanoparticles (average diameter: 3-30 nm) in this manner has been confirmed using UV-vis, fluorescence and energy-dispersive X-ray (EDX) spectroscopy analysis, and transmission electron microscopy (TEM). The hybrid films emit fluorescence at 530 nm that could be quenched on the silver nanoparticles surface via electron and energy-transfer processes..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
