We present a series of cationic membrane-targeted azobenzene molecules, with the aim to understand how variations in molecular architecture influence relative optical and biological properties. 1,4-Amino-substituted was chosen as switching unit while number linked alkyl chains their end-group were systematically varied. Their photophysics, membrane partitioning, electrophysiological efficacy st...

The basement membrane, a thin extracellular matrix, plays a critical role in tissue development and repair. Laminins are the major component of basement membrane and have diverse biological activities. We have identified various cell-adhesive peptides from laminins and their specific cell surface receptors. Polysaccharides, including chitosan, have been used as scaffolds, which regulate cellula...

Natural membrane vesicles (MVs) derived from various types of cells play an essential role in transporting biological materials between cells. Here, we show that exogenous compounds are packaged in the MVs by engineering the parental cells via liposomes, and the MVs mediate autonomous intercellular migration of the compounds through multiple cancer cell layers. Hydrophobic compounds delivered s...

membrane technology is used to separate water or solvents from salts or pollutants. this technique could be used for water treatment. for using of polyether sulfone (pes) hollow fiber membranes in water treatment processes, the pes hollow fiber membranes were prepared by dry-wet spinning method and heated in an oven at: 120°c, 150°c and 180°c. the effect of heating on performance of membranes w...

large unilamellar liposomes and multilamellar vesicles consisting of dmpc interacted with cationic phosphorus-containing dendrimers cpds g3 and g4. dsc and ζ -potential measurements have shown that liposomal-dendrimeric molecular recognition occurs due to the interaction between the complementary surface groups. calorimetric studies indicate that the enthalpy of the transition of the lipids tha...
