Jobin Yvon IBH have demonstrated for the first time
sub-nanosecond pulsed operation of LEDs at 280nm and 340nm. These new
NanoLED wavelengths are important for biosensor and protein research,
drug discovery and a range of analytical applications based on time
resolved fluorescence.
280nm is of particular interest because it matches the absorption maxima of the naturally fluorescent amino acids tryptophan and tyrosine. Tryptophan fluorescence is widely used as a probe of protein structure and dynamics. The 340nm LED overlaps the commonly used 337nm nitrogen line and has potential to replace nitrogen lasers in many applications.
NanoLEDs are miniature turn-key light sources that generate short optical pulses from <100ps to 1ns. All NanoLED sources are interchangeable and, with the addition of these new wavelengths, now provide plug-and-play operation from 280nm to 1.3µm.
