A 'super sensor' for cancer and CSIs

the electrochemical properties on the device," she says.

An early warning system for heart attacks

Enzymes released before the onset of a heart attack can also be detected, so this application has obvious uses in an operating room to give a physician warning of an impending attack during a procedure. It could be fitted into an implant like a pacemaker or another future device to alert the user to impending dangers, thus preventing sudden death.

Prof. Rishpon is also investigating the application of her technology to detect for pathogens in drinking water such as estrogen, a byproduct of the female birth control pill. The presence of these chemicals in America's drinking water is no minor health concern. And before tackling the problem, water officials need to know what they are up against. Prof. Rishpon's solution could be part of the future toolkit, she believes.

A bio-watchdog for the organic food industry

Detecting pesticides in food is another very desirable application. The organic food market is calling for more rigorous testing and regulations to ensure spraying doesn't occur on some farms, and that limits are not breached on others.

Commercial applications of Prof. Rishpon's basic research are already underway in many areas of diagnostics, but clearly there are more to come. "My super sensors are cheap, accurate and highly sensitive, and in principle they could detect and measure the presence of almost every biological-based material," Dr. Rishpon concludes. She is also collaborating on the device with scientists at Arizona State University.
