Biodegradable Chitosan Matrix Composite Reinforced with Titanium Dioxide for Biocidal Applications Conference Poster uri icon


  • Access to drinkable water is increasingly difficult in developing nations. According to the World Health Organization, more than 1.2 billion people lack access to this basic resource. The scientific community has risen to the challenge of developing innovating methods to purify water. In this challenging context, a novel chitosan and titanium dioxide biocomposite represents an appealing, economically viable solution to remove oils, heavy metals, and pathogen colonies from contaminated waters. This presentation will go over the study of a novel chitosan film matrix impregnated with anatase nanoparticles, which was capable of expressing antibacterial properties when exposed to UV light. A number of techniques allowed characterizing the biocomposite uniformity, corroborating the anatase crystal structure, and assessing the bonding type and nature of this bio-composite mixture. Different antibacterial tests with Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive) were completed via growth curve analysis and the Kirby-Bauer technique. The results of this encompassing study revealed that the bacterial growth was reduced by more than 50% while maintaining it other properties. SEM, FTIR and XRD were use to described the functional group, bonding type and nature of this biocomposite film.
