Growth and Some Enzymatic Responses of E. coli to Photocatalytic TiO2

Erdem A., Metzler D., Chou H.W., Lin H-Y, Huang C.P., University of Delaware, US

The effects of photocatalytic nano-TiO2 on the survival or die-off of E. coli (e.g. TK2) were investigated under ambient conditions. Experimentally, a 28-h E. coli culture was exposed to photocatalytic nano-TiO2 at various concentrations, e.g., [...]

Nano-Biotechnology toward Diagnostic Industry: Obstacles and Opportunities

Esfandyarpour H., Stanford, US

Biosensing of infectious agents should be ideally real-time, multiplexed, sensitive and specific. While no single device thus far have demonstrated superiority with respect to all these qualities, many of the upcoming nanomaterial-based sensors described in [...]

Synthesis and Characterizations of ZnO Nanorods Arrays for Solar Cell and Chemical Sensor Applications

Lupan O., Chow L., University of Central Florida, US

Synthesis of nanorod based solar cells and sensors are quickly directed towards developing alternative, lightweight, flexible nanodevices for wide area of commercial applications. Many research papers has been published, in recent years, in the area [...]

Serpentine Fluidic Structures for Particle Separation

Kole A.S., Lean M.H., Seo J., Palo Alto Research Center Inc, US

The above abstract is based on a novel technique for particle separation from liquid based solely on fluidic forces on the particles. No external force or filters are used for separation. The idea is scalable [...]

Fabrication of Perforated Membranes in Polymers by Imprint Lithography

Roychowdhury A., Park S., Louisiana State University, US

The ability to imitate architecture of naturally existing systems in an economical way is important because this will provide platform for various fundamental and applied research activities. One such structure is a perforated membrane having [...]

Conjugates of Enzyme-Magnetic Nanoparticles for Bioremediation*

Qiang Y., Sharma A., Paszczynski A., Meyer D., University of Idaho, US

Enzymes are proteins that function as biocatalysts in bioremediation. One of the major concerns in environmental applications of enzymes is their short lifetime. Enzymes lose their activity due to oxidation, which results in less stability [...]

Synthesis and Characterization of Magnetite Powders

Silverman B.M., Parasher S., Milner B., Zhou B., Headwaters Technology Innovation Group, US

Low-cost magnetic powders have been synthesized by Headwaters Technology Innovation Group. These powders exhibit a strong magnetic susceptibility mainly due to magnetite formation. The potential applications for this product range from cancer treatment, ferrofluids, to [...]
