Bringing UV excitation of small biomolecules and proteins to another level - pulsed high-power UV-LEDs with more than 40 times higher output power

Abstract

Steady-state and time-resolved photoluminescence measurements are powerful tools for getting in-depth information about the nature, characteristics, and environment of proteins and small biomolecules. The spectral region between 280 – 300 nm is significant for biology, life and materials science. Here we present the differences in steady state and time-resolved fluorescence measurements when using a regular pulsed UV-LED and new pulsed high-power UV-LED with a photoluminescence spectrometer.
