Impregnation of silver nanoparticles into bacterial cellulose for antimicrobial wound dressing
Bacterial cellulose was produced by Acetobacter xylinum (strain TISTR 975). Bacterial cellulose is an interesting material for using as a wound dressing since it provides moist environment to a wound resulting in a better wound healing. However, bacterial cellulose itself has no antimicrobial activity to prevent wound infection. To achieve antimicrobial activity, silver nanoparticles were impre...
متن کاملAntimicrobial effects of silver nanoparticles.
The antimicrobial effects of silver (Ag) ion or salts are well known, but the effects of Ag nanoparticles on microorganisms and antimicrobial mechanism have not been revealed clearly. Stable Ag nanoparticles were prepared and their shape and size distribution characterized by particle characterizer and transmission electron microscopic study. The antimicrobial activity of Ag nanoparticles was i...
متن کاملAntimicrobial effect of silver-impregnated cellulose: potential for antimicrobial therapy
BACKGROUND Silver has long been known to have antimicrobial activity. To incorporate this property into multiple applications, a silver-impregnated cellulose (SIC) with low cytotoxicity to human cells was developed. SIC differs from other silver treatment methods in that the leaching of silver particles is non-existent and the release of ionic silver is highly controlled. RESULTS Candida albi...
متن کاملComposite Hydrogels of Bacterial Cellulose - carboxymethyl Cellulose for Drug Release
Bacterial cellulose (BC) is a suitable material for biomedical applications due to its remarkable proprieties, such us: biodegradability, biocompatibility and ready availability. In this paper the swelling and drug release profiles from bacterial cellulosecarboxymethyl cellulose (BC-CMC) composite hydrogels were investigated, in the aim to use such systems in controlled drug delivery field. Ibu...
متن کاملGreen Process for Impregnation of Silver Nanoparticles into Microcrystalline Cellulose and Their Antimicrobial Bionanocomposite Films
A novel greener method to impregnate silver nanoparticles (AgNPs) into microcrystalline cellulose (MCC) by curry leaf (Murraya koenigii) extract is presented. The active reduction of silver ions by curry leaf extract was explored for the in situ impregnation AgNPs into MCC. Transmission electron microscopy (TEM) analysis of MCC coated with AgNPs showed the formation of silver particle sizes in ...
