Scientists have proven the effectiveness of the use of bioactive glass with silver to protect the wound from microbes. In this respect informs University of Birmingham.
Bioactive glasses are synthetic degradable biomaterials made of silicon. In particular, this type of glass is used to fill the sockets of extracted teeth, replace skull bones and in surgeries. Silver ions act as antibacterial agents, as they can penetrate the walls of bacterial cells and disrupt their life cycle. However, silver ions or nanoparticles in wound dressings tend to convert to silver sulfide or silver chloride, which can reduce and inhibit antimicrobial activity. success of treatment.
Sara Kuehne and colleagues set out to investigate the effect of silver-doped bioactive glass on biofilms. they were educated Pseudomonas aeruginosa, an antibiotic-resistant bacterium that colonizes chronic wounds. Experiments were conducted with fibrous bioglass used in transplantation to promote tissue growth.
It turns out that this method allows you to minimize the conversion of silver ions to silver chloride, thereby maintaining antimicrobial activity. The authors hope that their material will find application in dentistry or the treatment of serious and chronic wounds.
