Biointeractive fibres: A sustainable way of fighting bacteria by using antibacterial cellulosic fibres
2010 (English)Conference paper (Refereed)
Bacterial growth is a risk of infection. Antibiotics did long time seem to be a soln. to the problem, but now the consequences are seen, as antibiotic-resistant strains are evolving. The substances are also eventually released into the environment, where they often are harmful to living organisms. Antibacterial surfaces state another option. However, a majority of the now existing surfaces are of leaching type i.e. assocd. with the same problems as the antibiotics. The non-leaching are a safer option, but until now the fabrication has been a problem with use of e.g. org. solvents. We present a sustainable way of forming an antibacterial material onto cellulose by using the polyelectrolyte multilayer technique. By step-wise adsorbing oppositely charged polyelectrolytes in an aq. soln. contg. fibers, at room-temp., the surface of the fibers are modified. The result is a non-leaching material with bacteria inhibiting properties. Also the fabrication is quite safe, as polymers have shown lower toxicity to humans than their monomeric counterparts. Cellulose is an excellent substrate for antibacterial surfaces. It is easy to modify with the present technique and is in itself a sustainable materials, with multiple applications. Combined this gives us in total a new, antibacterial material which also opens up for sustainable cellulose-based products.
