Enterotoxin Sensor

This project is in collaboration with the US Department of Agriculture. The objective is to develop a low-cost device to detect enterotoxins in food.

The method that we are using improves on traditional fluorescence resonance energy transfer (FRET) by using a long-lifetime donor. The result is that the lifetime of the long-wavelength acceptor dye is extended. This is particularly useful in simplifying (and lowering the cost of) instrument design.
