Self-sterilizing ormosils surfaces based on photo-synzthesized silver nanoparticles.
Colloids and surfaces. B Biointerfaces, 2017Co-Authors: Lidiane Patrícia Gonçalves, Alejandro Miñán, Guillermo Benítez, Mónica Alicia Fernández Lorenzo De Mele, María Elena Vela, Patricia Laura Schilardi, Elias Paiva Ferreira-neto, Julia Cristina Noveletto, Wagner Rafael Correr, Ubirajara P. Rodrigues-filhoAbstract:Medical device-related infections represent a major healthcare complication, resulting in potential risks for the patient. Antimicrobial materials comprise an attractive strategy against bacterial colonization and biofilm proliferation. However, in most cases these materials are only bacteriostatic or bactericidal, and consequently they must be used in combination with other antimicrobials in order to reach the eradication condition (no viable microorganisms). In this study, a straightforward and robust antibacterial coating based on Phosphotungstate Ormosil doped with core-shell (SiO2@TiO2) was developed using sol-gel process, Chemical Tempering, and Ag nanoparticle photoassisted synthesis (POrs-CS-Ag). The coating was characterized by X-ray Fluorescence Spectroscopy (XRF), Field Emission Scanning Electron Microscopy (FE-SEM), Atomic Force Microscopy (AFM) and X-ray Photoelectron Microscopy (XPS). The silver free coating displays low antibacterial activity against Staphylococcus aureus and Pseudomonas aeruginosa, in opposition to the silver loaded ones, which are able to completely eradicate these strains. Moreover, the antimicrobial activity of these substrates remains high until three reutilization cycles, which make them a promising strategy to develop self-sterilizing materials, such as POrs-CS-Ag-impregnated fabric, POrs-CS-Ag coated indwelling metals and polymers, among other materials.
