E. A Sensor that may Improve Aspects of Health and Security

Narrator: This is Science Today. Significant steps have been taken towards developing a real time, portable diagnostic tool that can be used in homes, clinics and in the field. David Whitten, a researcher at the Los Alamos National Laboratory, says they've created a luminescent sensor that's capable of detecting various biological and chemical agents.

Whitten: The things that make our sensor very special are probably the fact that it's very fast and it's very simple. We think that we can provide, say sensor capsules of some sort that are ready to use and that all one has to do is check a sample which is suspected of containing a biological agent by adding it to our capsule.

Narrator: The goal is to develop a sensor that has many applications.

Whitten: We think it will really help in disease diagnosis, in preventing anti-terrorism and many other activities, so we think it will be very important in improving the overall prospects for health and security.
