What is FRET?

My research this summer took place in the Materials Engineering department at Drexel University.  I worked with Jennifer Atchinson who is a  graduate student in  the research lab of Dr. Jonathan Spanier.My project involved establishing experimental condtions that would allow us to observe the FRET between an inorganic quantum dot and an organic fluorophore.  These molecules must be aligned very close to one another (1-10nm) in order to observe this event.  In addition we placed these molecules on a monolayer of silver nanoparticles in order to enhance the FRET.
