“…As shown in Figure 6(a), the change in fluorescence intensity was indistinctive at low concentration of FG because of poor solubility and selfquenching property of pyrene. Once FG-C 18 self-assembled into micelles at a certain concentration, the pyrene was solubilized into the interior phase of micelles, which resulted in a sudden increase of fluorescence intensity [24]. The ratio of fluorescence intensity for emission spectrums (I 373 to I 384 ) was high in an aqueous medium, which was in accordance with the literature [25].…”

The objective of this study was to hydrophobically modify fenugreek gum (FG) and to further evaluate the potential application of the obtained derivative in liver-targeted drug delivery system. Stearic acid (C 18 ) was conjugated with FG (FG-C 18 ) by a simple esterification reaction. The obtained FG-C 18 was then characterized on its chemical structure by Fourier transform infrared spectroscopy and 1 H-nuclear magnetic resonance. The self-assembled nanomicelles (NMs) of FG-C 18 in water were prepared by an ultrasonication method. The average diameter and zeta potential of FG-C 18 NMs were 196.70 ± 6.12 nm and À31.79 ± 1.58 mV, respectively. FG-C 18 NMs appeared as spherical particles under transmission electron microscopy and possessed a critical micellar concentration of 0.042 mg/ml by pyrene fluorescence probe method. A low toxicity of FG-C 18 was revealed on both HepG2 and MCF-7 cells at 0.1-100 mg/ ml. Haemolysis of FG-C 18 was less than 5%. Cellular uptake of coumarin-6 into HepG2 cells was enhanced by treating with C6-loaded FG-C 18 NMs compared to free coumarin-6. These results suggest that FG-C 18 have a potential application for a liver targeted drug delivery. ARTICLE HISTORY

“…It had been accepted that the fluorescence emission spectra of pyrene had five fluorescence peaks including 373, 379, 384, 390, and 395nm. The critical micelle concentration of copolymer could be estimated by the changes of I 1 / I 3 as a function of copolymer concentration . The ratio of the fluorescence intensity at 373nm to that at 384nm strongly depended on the polarity of polymeric solution environment.…”

A kind of pH/UV sensitive terpolymer was prepared based on 2-(dimethylamino) ethyl methacrylate, hydroxyethyl methacrylate, and 7-(2-(4-vinylbenzyloxyl)-ethoxy)-4-methyl-coumarin. To well trace the self-assembly process and reversible photocross/de-cross-linking, the pH-and light-responsive behaviors at various conditions were investigated by dynamic light scattering and UV-Vis spectroscopic analysis, respectively. Besides, dual pH-and light-responsive coumarin-containing polymeric micelles could be used to manipulate the emulsion phases and trigger the solidification of emulsions, which was a big breakthrough in the development of particulate emulsifiers. The emulsifying performance could be predicted by the form of aqueous micellar solutions with a certain pH value before oil-water homogenization. Different to the effect of pH value lonely, the conversion from emulsification into solidification could be achieved with the synergetic effect of pH value and UV irradiation. This work might cast new insights on tuning emulsification/solidification performance just by adjusting pH value and UV irradiation time without the need for additives.[a] S.
