Visualization of quantum dot-electron donor conjugate uptake and processing by living cells

Clarke S.J., Hollmann C.A., Nadeau J.L., McGill University, CA

The interactions of semiconductor quantum dots (QDs) with living cells remain poorly understood. It is known that certain sizes (colors) of QDs penetrate more readily into subcellular compartments, such as the nucleus, or into bacteria. [...]

Preparation of Aggregation Stable Block Copolymer Nanoparticles for Simultaneous Drug Delivery and Imaging

Gindy M.E., Prud’homme R.K., Princeton University, US

We have developed a nanoparticle formation process based on rapid micromixing to produce high supersaturations, which we term Flash NanoPreciptiation.4, 5 This work introduces a novel approach that expands the applications of the Flash NanoPrecipitation [...]

Rapid Isolation of AMI Markers using Nanomagnetic Particles

Haik Y., Sista R., Qablan A., Chen C-J., Palanki S., United Arab Emirates university, AE

Due to the increasing number of AMI patients accompanied with a difficulty in diagnosing the anomaly, a major push to develop innovative approaches to tackle the recognition of myocardial infarctions has been noticed. Most of [...]

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 [...]
