BIOINTERACTIVE FIBRES-ANTIBACTERIAL CELLULOSE VIA POLYMER ADSORPTION
The world is in desperate need of new methods for controlling microbial growth.Antibacterial surfaces,with antibacterial polymers irreversible attached,is a promising alternative.By targeting the bacterial membrane,the risk of evolving resistant bacteria is reduced.The attachment of the polymers prevents unwanted leaching and keeps a high,active surface concentration.The making of such surfaces does however involve harsh reaction conditions and is thus unsuitable for use in large scale.Using the polyelectrolyte multilayer (PEM) technique we here electrostatically adsorb cationic antibacterial polymers.This takes place in aqueous solutions and in room temperature,making it an appealing alternative.Previous studies performed in our group have focused on model surfaces to get fundamental knowledge about the multilayer properties.Here the PEMs are applied on cellulosic pulp and tested for antibacterial properties against E.coli and B.subtilis.The obtained material was found to be antibacterial against both bacterial strains.These antibacterial fibers,produced in a safe,sustainable process,will give opportunities for new products and new applications.
