Bile-label 760 (BL-760), a novel near-infrared dye, has emerged as a promising tool for identifying biliary structures and leakage, owing to its rapid excretion and strong bile specificity. WebFluorescein (resorcinolphthalein) is a synthetic organic photoactive dye compound, first synthesized by von Bayer in 1871 [1]. Some of the advantageous features of fluorescein fluorophores are good water solubility and absorption, emission, and maximum brightness at physiological pH (Anthoni et al., 1995) [2].
