CHEMISTS' BIOSENSOR MAY IMPROVE FOOD, WATER SAFETY AND CANCER DETECTION

MANHATTAN -- A nanotechnology-based biosensor being developed by Kansas State University researchers may allow early detection of both cancer cells and pathogens, leading to increased food safety and reduced health risks.

Lateef Syed, doctoral student in chemistry, Hyderabad, India, is developing the biosensor with Jun Li, associate professor of chemistry. Their 1xbet online sports betting focuses on E. coli, but Syed said the same technology could also detect other kinds of pathogens, such as salmonella and viruses.

&1xbet online sports betting ;Kansas is a leading state in meat production and the poultry industry,&1xbet online sports betting ; he said. &1xbet online sports betting ;Any outbreak of pathogens in these industries causes huge financial losses and a lot of health risks. We want to prevent these outbreaks by detecting pathogens at an early stage.&1xbet online sports betting ;

Syed's recent research poster, &1xbet online sports betting ;Dielectrophoretic Capture of E. coli at Nanoelectrode Arrays,&1xbet online sports betting ; was named a winner at the recent Capitol Graduate Research Summit in Topeka. An article on this work has been accepted for publication in the scientific journal Electrophoresis.

For more than three and a half years, Syed's 1xbet online sports betting has focused on developing nanotechnology-based biosensors for pathogen detection and cancer biomarker detection. He began the 1xbet online sports betting as a doctoral student under the direction of Li, who has researched nanotechnology for 15 years.

&1xbet online sports betting ;Nanotechnology is a very exciting area,&1xbet online sports betting ; Li said. &1xbet online sports betting ;It really provides an opportunity to solve problems for health care and food safety. It can also be helpful for the environment and energy issues.&1xbet online sports betting ;

The project is a continuation of work that Li performed at the NASA Ames 1xbet online sports betting Center in California, where he spent seven years developing nanotechnology. While working in California, Li came up with the idea of developing a small chip to capture and detect pathogens.

When Li arrived at K-State in 2007 he continued the biosensor 1xbet online sports betting with Syed. Together they are working on developing biosensors for cancer diagnosis and pathogen detection. To develop these biosensors, the team uses carbon nanofibers, or CNFs, because they can form an array of tiny electrodes that is even smaller than bacteria and viruses. When these microbial particles are captured at the electrode surface, an electric signal can be detected.

&1xbet online sports betting ;A goal is to integrate this technology into a hand-held electronic device for pathogen detection so that we can use this device for in-line monitoring of water quality or food quality at industrial processing sites,&1xbet online sports betting ; Syed said. &1xbet online sports betting ;We have some preliminary results that indicate this technology is feasible, and I'm quite happy about that.&1xbet online sports betting ;

The project is supported by a Canadian-based company called Early Warning Inc., which provided the K-State 1xbet online sports betting team with 0,000 for two years as part of the developmental work. Recently, the project was also supported by the U.S. Department of Homeland Security Center of Excellence for Emerging and Zoonotic Animal Diseases, or CEEZAD, at K-State.

&1xbet online sports betting ;We're still working with the company and trying to eventually deliver this as a product to feed the market for water quality monitoring,&1xbet online sports betting ; Li said. &1xbet online sports betting ;You don't want people to drink contaminated water and get sick before you can do something. This research can be very helpful in the future as it can be applied in the very early stages before an outbreak spreads.

&1xbet online sports betting ;Nanotechnology is a diverse field, and includes such biosensor devices that we can develop in this lab at the university,&1xbet online sports betting ; he said. &1xbet online sports betting ;As long as we look for those opportunities, we can create something that is useful for Kansas and for people living here.&1xbet online sports betting ;
