The antimicrobial polymer PHMB enters cells and selectively condenses bacterial chromosomes [PDF]

, 2016
To combat infection and antimicrobial resistance, it is helpful to elucidate drug mechanism(s) of action. Here we examined how the widely used antimicrobial polyhexamethylene biguanide (PHMB) kills bacteria selectively over host cells.

Green Advances in Wet Finishing Methods and Nanoparticles for Daily Textiles. [PDF]

Macromol Rapid Commun
This overview presented nanoparticles (NPs) as a potential green alternative to hazard chemicals in wet textile finishing to provide antibacterial, flame, water, and UV protection. Upgrades to traditional processes included more innovative eco‐friendly technology to improve textile/NPs adhesion and product durability.

Update on the role of antiseptics in the management of chronic wounds with critical colonisation and/or biofilm [PDF]

, 2021
Biofilms play a major role in delaying chronic wounds from healing. A wound infiltrated with biofilm, or “critically colonised” wound, may become clinically infected if the number of microbes exceeds a critical level.

Intracellular Delivery of siRNA by Polycationic Superparamagnetic Nanoparticles

Journal of Drug Delivery, Volume 2012, Issue 1, 2012., 2012
The siRNA transfection efficiency of nanoparticles (NPs), composed of a superparamagnetic iron oxide core modified with polycationic polymers (poly(hexamethylene biguanide) or branched polyethyleneimine), were studied in CHO‐K1 and HeLa cell lines. Both NPs demonstrated to be good siRNA transfection vehicles, but unmodified branched polyethyleneimine ...
