A Study of the Antibacterial Activity of Polyhexamethylene Biguanide on Cotton Substrate
نویسندگان
چکیده
Interest in antibacterial textiles has been increasing recently. Different kinds of antibacterial textiles with different effectivity are being sold in the market. The influence of time on the antibacterial activity of such textiles is not known generally. The goal of this research was to study the mechanism of commercially available antibacterial agent meant for cotton with regard to the influence of concentration and time. E coli bacterium was chosen as the test microganism and tests were conducted according to the JIS L 1902 standard. The tests indicated that the antibacterial activity increased with increasing concentration of the agent on the fabric while there was a mixed trend in regard to the relation between time of action and the concentration of the agent on the treated textile.

Antibacterial activity of CuO - cellulose nano rods depends on anew green synthesis (cotton)
In this study CuO nano sheets were prepared using the cellulose extracted from green synthesis (cotton) as a novel me project. Structural properties were examined using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), and Ultra Violet (UV-Vis). The optimum copper oxide peak was at 2 theta 〖35.44〗^°corresponding to (1 ̅11) while for the cellulose was 〖22.8〗^°correspon...

INTRODUCTION To reduce the risk of local infections after surgical treatments for HPV infected cervical lesions, the post-operative regimen is generally based on the use of vaginal antimicrobial agents. AIM The efficacy and safety of polyhexamethylene biguanide-based vaginal suppositories was compared to a similar chlorhexidine-based treatment, in the post recovery regimen after surgical trea...
متن کاملPolyhexamethylene biguanide functionalized cationic silver nanoparticles for enhanced antimicrobial activity
Polyhexamethylene biguanide (PHMB), a broad spectrum disinfectant against many pathogens, was used as a stabilizing ligand for the synthesis of fairly uniform silver nanoparticles. The particles formed were characterized using UV-visible spectroscopy, FTIR, dynamic light scattering, electrophoretic mobility, and TEM to measure their morphology and surface chemistry. PHMB-functionalized silver n...
