Title (EN) NANOCRYSTALLINE CELLULOSE HYDROGELS FOR INHIBITION OF BACTERIAL ADHESION
(FR) HYDROGELS DE CELLULOSE NANOCRISTALLINE POUR L'INHIBITION DE L'ADHÉSION BACTÉRIENNE
Abstract:
(EN) The invention provides compositions for the inhibition of bacterial adhesion. The composition can include nanocrystalline cellulose (NCC) and a water-soluble polymer, which form an NCC hydrogel in water. The NCC hydrogel can be used to treat or coat devices such as a catheter, whereby the NCC hydrogel inhibits bacterial adhesion to the catheter surface to thereby inhibit biofilm formation and growth of bacteria on the catheter surface. The compositions and devices can thus be useful for inhibiting or preventing conditions such as urninary tract infections.
(FR) L'invention concerne des compositions permettant d'inhiber l'adhésion bactérienne. Les compositions peuvent comporter une cellulose nanocristalline (NCC) et un polymère hydrosoluble qui forment un hydrogel de NCC dans l'eau. L'hydrogel de NCC peut servir à traiter ou enduire des dispositifs, par exemple des cathéters, de sorte que ledit hydrogel de NCC inhibe l'adhésion bactérienne à la surface du cathéter et inhibe ainsi la formation de biofilm et la croissance des bactéries à la surface du cathéter. Les compositions et les dispositifs peuvent ainsi être utilisés pour inhiber ou prévenir des pathologies comme les infections urinaires.
