Effect of the incorporation of silica blow spun nanofibers containing silver nanoparticles (SiO/Ag) on the mechanical, physicochemical, and biological properties of a low-viscosity bulk-fill composite resin.

Objective: This work aimed at producing silica-blow-spun nanofibers containing silver nanoparticles (SiO/Ag) and investigating the effect of their incorporation in different proportions, with or without pre-treatment with a silane coupling agent, on the mechanical, physicochemical, and biological properties of a commercial composite low-viscosity bulk-fill resin.

Methods: The production of SiO/Ag nanofibers was confirmed by transmission electron microscopy (TEM) and energy dispersive X-ray analysis (EDX). A portion of the produced nanofibers was silanized.

In vitro antimicrobial and anticancer properties of TiO blow-spun nanofibers containing silver nanoparticles.

Nanosilver immobilized on TiO nanometric fibers (Ag/TiO) was produced by solution blow spinning and characterized using scanning electron microscopy, transmission electron microscopy, N adsorption/desorption, X-ray diffraction, X-ray photoelectron spectroscopy, water contact angle, and inductively coupled plasma emission spectroscopy analyses. The in vitro antimicrobial and anticancer activities of the produced nanofibers was also investigated. Ag/TiO nanofibers revealed a crystalline structure compatible with the rutile crystalline phase, as well as a mesoporous and superhydrophilic nature.
