Topic: Diagnostics & Bioimaging

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 [...]

Medical Imaging through Nanotechnology

Reflex-arc on a chip: An in silico cell culture analogue

Wilson K.A., Das M., Molnar P., Hickman J.J., University of Central Florida, US
To overcome the shortcomings of in vitro and animal models we are developing a microscopic cell culture analogue (microCCA) of the spinal reflex-arc. The present work draws on advances in a wide variety of technical [...]

Preservation of DNA and Protein Biofunctionality for Bio-MEMS & NEMS Fabrication

Trau D., Jie J., Sucher N.J., National University of Singapore (NUS), SG
Microfabrication processes especially in silicon are not compatible with biomolecules. For example, silicon processing is commonly performed at high temperatures and makes use of aggressive chemicals. Under these conditions biological materials are denaturated or decomposed. [...]

Design of a Wireless Passive Microsensor for Injection into the Human Brain

Spratley J.P.F., Hall P.S., Ward M.C.L., University of Birmingham, UK
The design of a sensor for injection into the human brain to aid sufferers of spinal injuries and neurological dissorders is outlined. It is powered and communicates by induction from an external coil, and incorporates [...]

Remote Manipulation of a Robotic Arm by Using Infrared Sensors

Chávez Rodríguez N.E., Esquivel Villar J., UNAM, MX
This project consists in adapting a remote operation system for a robotic arm by using infrared sensors to control its movements. A personal com-puter was used to send instructions to the robotic arm, instead of [...]

Stem Cell Differentiation Base on Acoustic Wave Sensor

Shih C-J, Tsai B-C, Ou K-L, Industrial Technology Research Institute, TW
This project was based on immobilizing bio-material. We used a new application for protein array and studied a new acoustic wave sensor which is based on silicon. We used the MEMS fabrication and the property [...]
