Fig. 2From: Near infrared fluorescent imaging of brain tumor with IR780 dye incorporated phospholipid nanoparticlesRelative fluorescent intensity of IR780-liposomes and IR780-phospholipid micelles. FI/FI0 was measured by fluorescence signal intensity of samples stored in the dark at 4 °C as compared with those stored in the dark at −20 °C (n = 3, Ex/Em = 745/815 nm).
