Antibacterial efficacy of chitosan- and poly(hexamethylene biguanide)-immobilized nanofiber membrane

International Journal of Biological Macromolecules, 2020
In this study, polyacrylonitrile (PAN) nanofiber membrane was prepared by an electrospinning technique. After alkaline hydrolysis, the ion-exchange nanofiber membrane (P-COOH) was grafted with chitosan molecules to form a chitosan-modified nanofiber membrane (P-COOH-CS). Poly(hexamethylene biguanide) (PHMB) was then covalently immobilized on P-COOH and

Covalently construction of poly(hexamethylene biguanide) as high-efficiency antibacterial coating for silicone rubber

Chemical Engineering Journal, 2021
Abstract Biofilm formation on biomedical devices & implants and the resulting bacterial induced infections are remaining severe clinic issues. Here, a facile layer-by-layer strategy to covalently construct poly(hexamethylene biguanide) (PHMB) as the high-efficiency bactericidal coating on silicone rubber (SR) has been developed.

Antimicrobial electrospun membranes of chitosan/poly(ethylene oxide) incorporating poly(hexamethylene biguanide) hydrochloride

Carbohydrate Polymers, 2013
Here, antimicrobial nanofibrous membranes were produced by electrospinning of chitosan/poly(ethylene oxide) (PEO) solution in the presence of poly(hexamethylene biguanide) hydrochloride (PHMB). The influence of PHMB on the electrospinnability and antimicrobial properties of chitosan/PEO nanofibers were studied.

Antibacterial efficacy of poly(hexamethylene biguanide) immobilized on chitosan/dye-modified nanofiber membranes

International Journal of Biological Macromolecules, 2021
This study aimed to develop a novel electrospun polyacrylonitrile (PAN) nanofiber membrane with the enhanced antibacterial property. The PAN nanofiber membrane was first subjected to alkaline hydrolysis treatment, and the treated membrane was subsequently grafted with chitosan (CS) to obtain a CS-modified nanofiber membrane (P-COOH-CS).

Toxic potential of Poly-hexamethylene biguanide hydrochloride (PHMB): A DFT, AIM and NCI analysis study with solvent effects

Computational and Theoretical Chemistry, 2022
In the current study, the toxic material Poly-hexamethylene biguanide hydrochloride (PHMB) has been characterized by UV–Visible and infrared spectroscopy in different solvent environments. The nature of the molecular interactions between solvent molecules and PHMB via hydrogen bonds has been investigated using the Atoms in Molecules (AIM) and non ...
