Antibacterial Surface Treatments Based on Silver Cluster Deposition

Torna indietro

Abstract

Process to obtain antibacterial surfaces by silver deposition in the form of firmly bonded small particles and to the antibacterial substances obtained by aforementioned treatments. Silver deposition is obtained by surface impregnation of natural or synthetic material in an alcoholic solution with silver salt and, later, by their exposure to UV-rays until metal silver clusters form as a result of silver ions reduction on the material surface. The invention relates to the obtained antibacterial substances. The simple preparation of the antibacterial material makes the whole process easier both for required time and for costs: the needed devices are just a UV lamp and an Ultrasound bath.
