Abstract:
We developed a facile and green bio-inspired strategy to fabricate silver nano-particles growth in-situ on different scaffolds materials, building novel heterostructures for promoting their antibacterial activities and durability. Firstly, fluorinated graphene oxide (FGO) nanosheets, layered molybdenum disulfide (MoS2), and layered tungsten disulfide (WS2) were exfoliated by chemical liquid with intense sonication. And silicon dioxide (SiO2) nano-spheres were prepared via wet chemical method. Then, silver nanoparticles were grown onto those surfaces of layered nanosheets and nano-spheres, hybridizing three dimensional hetero-architectures. The obtained silver-hybridized nanoarchitechtures were further analyzed by TEM and EDS. Additionally, three bacteria were applied to evaluate their antibacterial property, illustrating distinctive antibacterial effects, expecting to explore more applications in water disinfection and food packing fields.
