Em <400 nm 紫外发射光荧光探针

Naphthoresorcinol (1,3-Dihydroxynaphthalene) 是一种荧光染料 (λex=330 nm, λem=380 nm)，与 NPPD (一种示踪剂) 和浓 HCl 反应显示出红色。它也能够作为测定碳水化合物的背景电解质 (BGE) 。

Pyrene是一种具有致癌性的多环芳烃(PAH)和灵敏的蓝色荧光团，Ex=338nm，Em=375nm，可用于检测蛋白质和脂质的相互作用和构象变化，也可以作为电子供体材料。

NIR-βgal-2，一种针对β-半乳糖苷酶的近红外荧光探针，特点是具有高度的灵敏性，适用于乳腺癌中β-半乳糖苷酶的可视化研究。

DPPP is a probe that reacts stoichiometrically with hydroperoxides to yield the fluorescent molecule diphenyl-1-pyrenylphosphine oxide (DPPP-O). Plasma levels of lipid hydroperoxides of phosphatidylcholine, phosphatidylethanolamine, triglycerides, and cholesteryl esters have been measured by HPLC with a post column detection system using DPPP. DPPP has also been used as a fluorescent probe for the detection of low density lipoprotein and cellular oxidation. Fluorescence of DPPP-O can be monitor using excitation and emission wavelengths of 351 nm and 380 nm, respectively.
