We demonstrate the plasmon-selective and driven deposition of (bipyramidal) Au nanoparticles on transparent substrates (glass coverslips) utilizing total internal reflection (TIR) illumination. Near-IR laser light undergoing TIR at a glass-water interface causes colloidal Au bipyramids to irreversibly deposit onto the glass surface. We demonstrate that the deposition process has particle (i.e.,...

Background and Objective: Since the preparation of antibacterial materials in dentistry is very noticeable, therefore, we tried to evaluate this effect on Streptococcus mutans by addition of silica nanoparticles to LCGI (light curing glass ionomer). Materials and Methods: In this in vitro study, we had five LCGI experimental groups that contained 0, 0.2, 0.5, 1, and 2% (w/w) of silica nanopa...

Natural-based composite’s progress as carriers has revealed many benefits in biomedicine, notably the construction field, synthetic biology, and genetic engineering. Compared to analogous composites without nanoparticles, incorporating nanoparticles into polymeric materials improved architectural performance, physiological connections, ecological features. The major goal of current investigatio...

Glass-ceramics (GCs) are materials obtained from the crystallisation of functional phases in glass, and have a structure that the crystallised phase embedded in the glass matrix. Glass-forming oxides are commonly added to the functional phases to improve the stability of precursor glass; however, the issue of glass-ceramics permitting the presence of residual phases resulting from addition is r...
