Environmental sanitation is crucial especially in organizations such as hotels that cater to medical tourism, daycare facilities, and nursing homes. This is because the majority of the population may be immunocompromised. The goal of this study was to investigate the efficacy of Titanium Dioxide Nanoparticles (TDN) against environmental microorganisms found on hotel room fomites (e.g. remote control, door knobs, and bathroom floors) before and after treatment with TDN with hotel room blinds open (since TDN is a photocatalyticcompund). Following this, the effect of TDN was studied on coupons (porous=carpet and non-porous=Formica) inoculated with specific pathogenic bacteria (Salmonella, Listeria, and E. coli O157:H7) and viral surrogates (MS2). These studies were carried out under dark and light conditions. The results showed a reduction in Salmonella (98.0.. View More»
