In vitro biocompatibility studies of antibacterial quaternary polymers.

Quaternary Ammonium Salts of Poly(N,N-dimethylaminoethyl methacrylate) as an Efficient Antibacterial Agent for Polylactide Textiles

Improved antibacterial activity and biocompatibility on vancomycin-loaded TiO2 nanotubes: in vivo and in vitro studies

The goal for current orthopedic implant research is to design implants that have not only good biocompatibility but also antibacterial properties. TiO2 nanotubes (NTs) were fabricated on the titanium surface through electrochemical anodization, which added new properties, such as enhanced biocompatibility and potential utility as drug nanoreservoirs. The aim of the present study was to investig...

Preparation and in-vitro Antibacterial Evaluation of Electroless Silver Coated Polymers

Long-term use of indwelling medical catheters has often been hindered by catheter-associated nosocomial infections. In this study the effectiveness of silver coating of polystyrene and polyethylene polymers was investigated. Polymer pieces of 2 cm2 each were coated with a thin layer of silver using electroless plating technique. Silver-coated polymers were challenged with cultures of four diffe...

Quaternized Chitosan as an Antimicrobial Agent: Antimicrobial Activity, Mechanism of Action and Biomedical Applications in Orthopedics

Chitosan (CS) is a linear polysaccharide with good biodegradability, biocompatibility and antimicrobial activity, which makes it potentially useful for biomedical applications, including an antimicrobial agent either alone or blended with other polymers. However, the poor solubility of CS in most solvents at neutral or high pH substantially limits its use. Quaternary ammonium CS, which was prep...
