Access to drinkable water is difficult in areas struck by environmental disasters. The present research involves the use of a low cost functional biocomposite made of chitosan and titanium dioxide (TiO2) as an alternative for removal of pathogen colonies. We synthesized our biocomposite by adding chitosan, deionized water, and TiO2 into a homogeneous solution that is conveniently treated afterwards. The biocomposites were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy. To evaluate the antibacterial capacity of our biocomposite, we studied its effect on Staphylococcus aureus and Escherichia coli. The microorganisms underwent different testing conditions, i.e. TiO2 and UV light, only UV light, only TiO2, and the chitosan biocomposite bearing different TiO2 concentrations. The biocidal effectiveness of this functional biocomposite was assessed via a growth curve analysis. The research revealed that TiO2 nanoparticles inhibit the growth of both bacteria at low cell concentrations.
