Quantum Dots Research Leads to New Knowledge about Protein Binding in Plants

UC Riverside researchers from the Departmentsof Chemical and Environmental Engineering, Mechanical Engineering andBotany and Plant Sciences have worked together to discover a way toutilize to uncover new knowledge about the binding of a protein at the growingpollen tube tip. This protein plays a critic...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

In what may be one of the first medical uses of nanotechnology, a chemist and a doctor who specializes in infectious childhood diseases have joined forces to create an early detection method for a respiratory virus that is the most common cause of hospitalization among children under five. Respiratory syncytial virus (RSV) sends about 120,000 children to the hospital in the United States e...

New nanosensor uses quantum dots to detect DNA

Using tiny semiconductor crystals, biological probes and a laser, Johns Hopkins University engineers have developed a new method of finding specific sequences of DNA by making them light up beneath a microscope. The researchers, who say the technique will have important uses in medical research, demonstrated its potential in their lab by detecting a sample of DNA containing a mutation lin...

Connect the Quantum Dots

A new study, published today in the current issue of the Proceedings of the National Academy of Sciences has significant implications for the design of disease markers and the development of chemoreceptors used in human biomedical research. The groundbreaking study, entitled, "A Mechanism to Signal Receptor-Substrate Interactions with Luminescent Quantum Dots", demonstrates that quantum dots can...

DOTS For Tuberculosis TO Cover Entire Country

The Directly Observed Treatment Short-course (DOTS) tuberculosis control programme will cover the entire country by November 2006 said union Health Minister Anbumani Ramadoss said here Sunday.// "The drugs for the DOTS programme will be made available even in petty shops and dhabas in remote areas," said the minister at a function here to open a new HIV vaccine trial and patient care f...

Health Experts Discuss Effect of DOTS on TB Control in India

Some health experts in India are questioning the efficacy of the DOTS program to control the spread of tuberculosis in the country. The increasing number of TB cases recorded throughout the country indicates that there are problems with how the DOTS strategy has been implemented, according to the Indian Medical Association. India routinely has implemented various TB control program...
