pH responsive adhesion of phospholipid vesicle on poly(acrylic acid) cushion grafted to poly(ethylene terephthalate) surface

Magnetic-nanoparticle-modified paclitaxel for targeted therapy for prostate cancer

“…FT-IR (TENSOR Model 27, Bruker) spectroscopy was recorded by KBr sample holder method. The concentration of carboxyl group on the surface of SPAnH/MNPs was measured by TBO method [39]. The solution was mixed by vortexing for 1 h, then sonicated for another 1 h. PTX immobilized on the surface of SPAnH/MNPs (i.e., bound-PTX) was separated from the solution and washed with pure alcohol and DI water; bound-PTX was washed with DI water to remove residual alcohol and the nanoparticles were dispersed in 0.2 mL DI water.…”

Progress in Mimetic Studies of Cell Adhesion and the Mechanosensing

“…However, at this point in time, only a few studies have been able to obtain conclusive results. [32,64,65] It has been shown that by incorporating integrin receptors into a supported bilayer and depositing this membrane on a substrate covered by several layers of cellulose, the majority of integrins, which have their binding site exposed toward the bulk of the sample, remain mobile. When these integrins were presented to their binding partners (RGD sequence), carried by vesicles, specific adhesion could be studied and the results compared to the case when the integrin is immobilized.…”

Complexation of cationic polyelectrolyte with anionic phospholipid vesicles: Concentration, molecular weight and salt effects

“…While zwitterionic phosphatidylcholine can be regarded as the main component of erythrocyte membranes, negatively charged phosphatidylglycerol is widely used to mimic the membranes of bacteria, plant leaves or algae [1,2]. To increase the physical and biological stability of vesicles or to modify the vesicle surface properties, polymer has often been employed [3][4][5][6][7][8]. For charged vesicles, polyelectrolyte has attracted much attention due to its unique stabilizing and reversible network forming properties via electrostatic interaction [9][10][11][12].…”
