查询词典 micelle

Compared with HA in water-contained organic solvents, the pigment in micelle had higher pKa value and higher fluorescence quantum yield. Moreover, the quantum yield of active species produced from photosensitization, 1O2 and ·OH, increased as well. As a result, the photosensitivity of HA was enhanced.

相对于含水有机体系，HA在胶束中基态的 pKa值升高，荧光量子产率增大，光敏反应产生的活性中间体1O2 和·OH的产额增加，从而提高了其光敏活性，这在光敏损伤作用中具有重要的生物学意义。

The dissolubility of PPLA in water was (2.16～4.32)×10－2 mg·mL－1 according to eye judgment. The critical micelle concentration was 2.16×10－2 mg·mL－1 obtained from a fluorospectrophotometer. The self-assembled aggregates of PPLA in water were nanoscale spheres observed by a transmission electron microscope. The particle size and zeta potential tests by dynamic light scattering revealed that during preparation, the ratio of hydrophilicity/hydrophobicity, the aqueous medium and the pH had great influences; while dilution, freezing and pH change to basic condition had no effect after preparation, but pH change to acidic condition made the nanoparticles precipitate.
