Photocatalytic Air Disinfection to Destroy Airborne Hazardous Microorganisms The biggest danger from biohazards, such as anthrax, comes when they become airborne and spread through the building ventilation system. Conventional air filtrations systems are inadequate to provide a satisfactory solution. Drastic measures, such as fumigation with Chlorine Dioxide, have serious consequences. Photocatalytic disinfection technology developed by Dr. Goswami has been shown to be effective, however, the technology needs improvement to be effective against bioterrorism. It is proposed to improve the photocatalytic air disinfection technology to reduce the time needed for complete oxidation to a fraction of a second. The improved photocatalytic technology incorporated with HEPA and electrostatic air filters will provide complete solution to removing and neutralizing biohazards from indoor air. The proposed improvements will include active removal electrons from the catalytic surface, thereby improving the reaction rate, and identifying catalysts that may utilize visible light for activation.

To design advanced functional materials for photocatalysis in remediation and slurries in chemical mechanical polishing, we have focused on composite materials of inorganic nanoparticles such as TiO 2 and CeO 2 embedded within microspheres of a responsive polymeric network. Recent Research Projects: ‣ Chemically Selective Self-Assembled Surfaces and Guest-Host Recognition ‣ Engineering Nanoscale Constructs of Metallic Nanoparticles and Stimuli-Sensitive Polymers ‣ Tailoring Stimuli Sensitive Polymeric Gels and their Composites with Inorganic Nanomaterials ‣ Using Gold Nanoparticles and Nanorods for Diagnostic and Sensing Applications ‣ Transforming the Educational Experience of Transfer Students in Chemical Engineering 2000nm Engineering Nanoscale Constructs of Nanoparticles and Nanorods Responsive nanoscale constructs of metallic nanoparticles and synthetic biopolymers are of great interest in nanobiotechnology. We focus on directing the self-assembly of gold nanoparticles as it is extremely relevant to sensors, biomedicine, diagnostics, and nano-electronics.
