Diamond Film May Enable Critical New Sensors For Bioterror

MADISON - In this time of the chronic threat of terrorism and the possibility of war with an adversary who may be armed with biological weapons, high on the wish list of security agencies and battlefield commanders is a quick and easy way to detect the presence of dangerous biological agents.

Now, with the help of a novel diamond film developed by chemists at the University of Wisconsin-M......

Because diamond films can be deposited on silicon, the stuff of which computer chips and other microelectronic devices are made, it provides a bridge between the world of miniature electronics and biology, which requires a che......

Other materials such as gold, glass and glassy carbon proved either unstable or difficult to integrate with silicon.

The biologically modified diamond films, on the other hand, have proved to be remarkably durable, able to withstand multiple cycles of processing DNA, genetic material that can be diagnostic of such ......

In addition to Hamers, Smith and van der Weide, Wensha Yang a UW-Madison graduate student in chemistry, played a key role in the research. Other UW-Madison co-authors include Wei Cai, Tami Lasseter and Tanya Knickerbocker. The diamond films c......
