TiO2 photocatalysts have been found to kill cancer cells, bacteria and viruses under mild UV illumination, which offers numerous potential applications. On the other hand, Ag has long been proved as a good antibacterial material as well. The advantage of Ag-TiO2 nanocomposite is to expand the nanomaterial's antibacterial function to a broader range of working conditions. In this study neat TiO2...

Abstract In this work, functionalized reduced graphene oxide–silver (FrGO–Ag) nanocomposite was synthesized to enhance the antimicrobial activity and biocompatibility of FrGO for infected wound burn treatment. The reduction GO FGO confirmed by removal some oxygen functional groups (carbonyl epoxy groups) as revealed Fourier transform infrared (FTIR) spectra. face-centered cubic (fcc) silver nan...

Fluorescent nanocomposite films were prepared by solution mixing of polyvinyl alcohol (PVA) and tryptophan functionalized silver (AgTrp) nanoparticles. Synchrotron excitation deep-ultraviolet (DUV) fluorescence imaging was used to follow the distribution AgTrp nanoparticles within polymer matrix. Pronounced growth dendrite-like structures in presence confirmed bright field as well with atomic f...

Silver nanostructures as an effective antibacterial materials were synthesized via three various hydrothermal, sono-chemical and microwave methods using water as a green solvent. Then Chitosan-Ag polymer based nanocomposites were made by a fast chemical procedure. The influence of power, temperature and time on the morphology and particle size of the products was investigated. Scanning electron...

Photochromic reaction dynamics in silver nanoparticles embedded inmesoporous titaniumdioxide thinfilms is investigated by combining real-time grazing incidence small-angle x-ray scattering (GISAXS) and optical transmissionmeasurements duringUV–visible laser exposure cycles.While GISAXS probes changes in the particle size distribution, transmittancemeasurements are sensitive to spectral changes ...

In recent years natural polymers have been widely used in biomedical applications. Application of natural and biocompatible polymers in wound dressing, medical sutures and tissue engineering are extensively growing. Additional properties are provided when metal nanoparticles such as silver and gold are incorporated in to the fibers. However, nowadays nanofibers due to their inherent properties ...

We theoretically investigate the properties of optical propagation in one-dimensional soft photonic crystals based on ferrofluids using the transfer matrix method. The proposed structure is composed of an alternating ferrofluid layer and a dielectric layer. Ferrofluids are composed of suspended ferromagnetic nanoparticles coated with silver, which has a frequency-dependent dielectric function. ...
