Abstract

Terbium-dipicolinic acid can be used to enhance the UV fluorescence detection of selected biological agents and endospore cells. We are using new tunable UV laser near 220nm-280nm to optimize the excitation wavelength and detection sensitivity, and studying the acid solution/buffer mix to optimize the fluorescence yield. Enhancements on the order of a factor of 20 have been observed so far.
