This work is focused on the fabrication of a human breathing sensor based on in situ synthesis of silver nanoparticles (Ag NPs) inside a polymeric coating (LbL assembly) on an optical fiber core. The Ag-NPs were created using a synthesis protocol consisting of a loading step of the Ag+ cations into the polymeric film and a further reduction step using Dimethylamine Borane (DMAB). The Ag-NPs amount increases when the number of loading /reduction cycles is...
