Summary: Supramolecular plasmonic polymer nanocomposites were synthesized by in situ formation of gold nanoparticles in a poly(vinyl alcohol) hydrogel using plant-derived gallic acid as reducing agent. The size and shape of the nanoparticles were tuned by changing the concentration of Au3+. The optical and chemical properties of the nanocomposites were analyzed experimentally and theoretically. The viscoelastic behavior of the hydrogel and its potential as a sensing platform were also investigated.

Summary: The development of sustainable high-performance materials based on nanocellulose has received great attention. In this study, nanocellulose-based composite films with highly conductive and antibacterial properties were developed by adding reduced graphene oxide (rGO)/silver nanoparticles (AgNPs) to cellulose nanofiber films through a vacuum filtration process. The reduction effect of gallic acid on the chemical structure and electrical conductivity of the composites was investigated. The prepared composite film with a specific ratio of rGO/AgNPs to cellulose nanofibers showed superior tensile strength and electrical conductivity, as well as strong antibacterial effects against Escherichia coli and Staphylococcus aureus.
