Negatively charge antibacterial materials

As a new type of functional polymer materials with antibacterial activity, pyridinium-type polymers possess many unique properties in the interaction with bacteria, viruses and other negatively charged species, thus exhibiting the potential of finding wide application in many fields such as microbiology, biotechnology, water treatment, etc. The antibacterial activities of soluble and insoluble pyridinimn-...

Cationic polymer-functionalised gold NP have large concentrations of positive charge, which promote their adsorption onto negatively charged bacterial membranes via electrostatic interactions. This kind of antimicrobial material, with effective antibacterial activity and better biocompatibility, can promote the healing of microbially infected wounds and could have promising applications in the biomedical field.
