Abstract

We demonstrate measurement of the intrinsic fluorescence decay of a protein excited with a new and inexpensive optical source based on a light emitting diode (LED) giving 600 ps pulses at ∼280 nm. We believe this source will offer significant new capabilities for fluorescence research and development.
