WebNov 1, 2007 · Depending on the functional groups introduced into the molecule, fullerenes can effectively photoinactivate either or both pathogenic microbial cells and malignant cancer cells. The mechanism appears to involve superoxide anion as well as singlet oxygen, and under the right conditions fullerenes may have advantages over clinically applied ... WebThe emergence of antibiotic resistance amongst pathogenic bacteria has led to a major research effort to find alternative antibacterial therapies. A new promising approach to treat bacterial infections is called bacterial photodynamic inactivation (PDI). This is based in the administration of a photosensitizer, which is preferentially accumulated in the microbial … portland tennessee city council

WebBackground: Pathogen Reduction Technologies (PRTs) are broad spectrum nucleic acid replication-blocking antimicrobial treatments designed to mitigate risk of infection from blood product transfusions. Thiazole Orange (TO), a photosensitizing nucleic acid dye, was previously shown to photoinactivate several types of bacterial and viral pathogens in RBC … Webphotoinactivate E. coli. If so, which one is better at photoinactivation of this bacterium: Ta 2 O 5 or TaON? The hypothesis is that TaON will perform better due to its smaller bandgap and higher promise in photocatalytic ability. This hypothesis is rooted in calculations for photon energy E (hv) and the excitability of TaON within the visible ...
