Sobre IBD

Dans cet ouvrage, des nanoparticules d’argent et d’oxyde de zinc ont été synthétisées in situ dans le réseau d’hydrogel de gomme d’acacia/poly(acrylate) à l’aide d’approches de réduction et hydrothermiques respectivement. Les nanoparticules métalliques synthétisées ont été caractérisées par résonance plasmonique de surface (SPR), diffraction des rayons X (XRD), spectroscopie infrarouge à transformée de Fourier (FTIR), microscopie électronique à transmission (TEM), analyse thermogravimétrique (TGA) et microscopie électronique à balayage (SEM). Le comportement d’absorption d’eau des hydrogels GA/poly(SA) chargés d’Ag et de ZnO a été étudié dans une solution saline tamponnée au phosphate (PBS) de pH 7,4 à 37 °C. Les données d’absorption d’eau ont été analysées à l’aide de divers modèles cinétiques. Enfin, l’action antimicrobienne des nanocomposites a été étudiée en utilisant E. coli comme bactérie modèle.
