Gamma irradiation induced surface modification of silk fabrics for antibacterial application

Surface Modification of Polyester Fabrics with Vinyltriethoxysilane

Surface modification of polyester fabrics was studied aiming at improving the water repellency property. Vinyltriethoxysilane (VTES) was employed as surface modifying agent. Prior to application, VTES was prepared in aqueous emulsion using cetyltrimethylammoniun bromide (CTAB) as an emulsifying agent. The application of VTES emulsion was carried out using a padder and followed by curing at 150C...

Surface Modification Methods for Improving the Dyeability of Textile Fabrics

Surface Modification of Polymer Materials Induced by Laser Irradiation

We report on the surface modification effects using allyl‐diglycol CR39 polymer induced by laser irradiation at 157 nm F2 laser (VUV) and 248 nm KrF laser. The motivation is to investigate the ablation effects on this polymer in optical waveguides application the ablation effects on this polymer in optical waveguides. Fabrication of waveguides has been observed using continuous wave (CW) at 244...

Silk fibroin/hydroxyapatite composite hydrogel induced by gamma-ray irradiation for bone tissue engineering

BACKGROUND In this study, silk fibroin (SF) composite hydrogels containing hydroxyapatite (HAP) nanoparticles (NPs) for bone tissue engineering were fabricated using gamma-ray (γ-ray) irradiation treatment. During the irradiation, the HAP dispersed SF solution was changed to the chemically crosslinked SF hydrogel. METHODS Distribution of HAP NPs in the SF hydrogel was examined by SEM imagery ...

Antibacterial Modification of Intravascular Catheter Surface for the Prevention of Catheter-Associated Infection

Objective: Intravascular catheter-associated infection has been increasing hospitalization in post-surgery patients mainly due to microbial colonization of the catheter surface and formation of a superficial biofilm layer. The present study is aimed in developing an effective antibacterial device which can prevent colonization of organisms by modification of catheter. Methods: In the present st...
