Morphological manipulation of PC liposome by controlled bolaamphiphile doping.

The morphological characterization of aqueous dispersions of PC amphiphile and bolaamphiphile AEC was observed by transmission electron microscopy, the measurement of the liposomal membrane fluidity, differential scanning calorimetry, 5(6)-CF release from liposome and zeta potential measurement. Results indicate that the bolaamphiphile AEC can be included within conventional egg-PC liposome bilayer, which leads to the decrease of liposomal membrane fluidity (P) and the release behavior of 5(6)-CF. This behavior could be due to the property of bolaamphiphile AEC and the good miscibility of bolaamphiphile AEC with PC.

Simulation of human vision by image evolution in light-excitable nonlinear optical mediums.

The nonlinear optical membrane used for image processing was prepared using tetraethyl silicate by sol-gel method under mild conditions. Ru(bpy)3Cl2 (bpy, bipyridine) was immobilized in the sol-gel matrix. This light-excitable membrane containing Ru(bpy)3Cl2 as photocatalyst could catalyze the Belousov-Zhabotinsky reaction by illumination. Our results indicated that a fine-definition image processing could be autoperformed when projecting a picture on this medium. The imaging process was an image evolution process, which was similar to that of the human vision process.
