The Interaction of Protein-Modified Nanodiamond with Bacterial Cells

Perevedentseva E.V., Tu J.-S., Cheng C.-L., Cheng C.-Y., Chung P.-H., Chang H.-H., Cheng C.-L., Cheng C.-Y., National Dong-Hwa University, TW

The possibility of using nanodiamond as bioactive nano-probes for bio-object labeling and treatment is demonstrated. The conjugation of Nanodiamond crystals and bio-molecules are comparatively new but promising subject of interest for bio-applications, due to their [...]

Surface Plasmon Spectral Shifts of Functionalized Gold Nano particles for the Use in Biosensors

Chatterjee S., Moriarty G., Gersten B., Queens College, CUNY, US

Recently there has been interest in the use of gold nanoparticles as a colorimetric method to detect the hybridization event of DNA [1-4]. The method uses the physical phenomena that nanoparticles of gold exhibits the [...]

New Applications of Nanoparticles in Cardiovascular Imaging

Sharma R.R., FAMU-FSU College of Engineering, US

Nanotechnology involves working at the atomic, molecular, and macromolecular levels including imaging. Recently, four areas have emerged in cardiovascular imaging:1.Targeted therapeutics: delivering drugs where they are needed; 2.Tissue engineering to replace defective valves, damaged heart [...]

CdSe Nanoparticles Modified with Water-soluble Terpolymers and their Application to Biomarkers

Tsutsumi H., Yamada M., Yasui M., Yamaguchi University, JP

Fluorescent labeling reagents are used as diagnosis and research reagents that label specific protein, antigen, antibody, and DNA. However, the chromophoric groups are not stable under long-time Ultra Violet (UV) excitation measurement condition. Nanometer-sized semiconductor [...]

Change of 7Be decay rate in exohedral and endohedral C60 fullerene

Ray A., Das J.J., Das P., Saha S.K., Das J.J., Das P., Madhavan N., Variable Energy Cyclotron Center, IN

We have measured the change of decay rate of 7Be in different environments including in atomic clusters such as fullerene C60. It has been found that the decay rate depends on the geometrical position of [...]

A highly sensitive fluorescent immunoassay based on avidin labeled nanocrystals

Sin K-K, Chan C.P-Y, Pang T-H, Seydack M., Renneberg R., the Hong Kong University of Science and Technology, HK

Nanocrystals of the fluorogenic precursor fluorescein diacetate (FDA) were applied as labels to enhance assay sensitivity in our previous studies. Each FDA nanocrystal can be converted into ~2.6 x 106 fluorescein molecules, which is useful [...]

Nanotechnology and the Water Market: Applications and Health Effects

Mowat F.S., Tsuji J., Exponent, US

Nanotechnology has an enormous potential for creating cost-effective, simple, and efficient tools for addressing water supply challenges, while preventing the creation of potentially toxic by-products. Applications include water disinfection and filtration, real-time and remote monitoring, [...]

Economic and Environmental Tradeoffs in SWNT Production

Healy M.L., Tanwani A., Isaacs J.A., Northeastern University, US

Assessment of economic and environmental attributes of nanomanufacturing during process development has significant potential to contribute to the quality and effectiveness of the processes, and will lead to development of competitive, safe and environmentally responsible [...]

Preparation and Characterization of Various Nanofluids

Williams W.C., Bang I.C., Forrest E., Hu L.W., Buongiorno J., Massachusetts Institute of Technology, US

As part of an effort to evaluate water-based nanofluids for nuclear applications, preparation and characterization has been performed for nanofluids being considered for MIT’s nanofluid heat transfer experiments. Three methods of generating these nanofluids are [...]

Interaction between Artificial Mucin Layer and Stimuli-Responsive Nanogel Particles for the Oral Peptide Delivery Observed in Simulated Intestinal Solutions by Using Colloid Probe AFM Method

Kamiya H., Yoshimura M., Tsukada M., Ichikawa H., Fukumori Y., Tokyo University of Agriculture and Technology, JP

In order to characterize and control the adhesive behaviors of nanometer scaled stimuli-responsible gel particles designed for oral peptide delivery, their interaction with artificial mucin layer in the small intestinal solutions was determined by the [...]
