Preparation and characterization of pore-suspending biomimetic membranes embedded with Aquaporin Z on carboxylated polyethylene glycol polymer cushion

Nature gives the best solution for desalination: Aquaporin-based hollow fiber composite membrane with superior performance

“…4a, b) show that these embedded vesicles retained their intact spherical shape even after experiencing hydraulic pressure tests, suggesting a good mechanical strength and stability of proteoliposomes. This observation was in accordance with several studies reported previously [11,15,29]. It is believed that the polyamide layer in combination with the porous substrate also helped those embedded vesicles withstand the external applied force.…”

Study on water transport through a mechanically robust Aquaporin Z biomimetic membrane

“…(8). As shown in our previous study, the immobilized vesicles maintain spherical morphology after the FO tests, indicating that the vesicles are effectively crosslinked and mechanically stable [12].The vesicle with a higher concentration of interior solute will be subjected to a higher hydrostatic pressure in the FO mode tests, which can also be observed from our calculation in Fig. 4.…”

“…The first design is to coat a thin layer of lipid bilayer or amphiphlic block copolymer layer embedded with Aqp on the surface of porous support. These include (1) proteopolymersomes rupture onto the ultra-filtration membrane support via covalent bonding and (2) charged lipid vesicles rupture onto the nanofiltration membrane support via electrostatic attraction [10][11][12][13][14]. The selective layer of such design is significantly thinner than that of the conventional polymeric membranes, which could facilitate the fast transportation of water molecules [14].…”

Preparation of high performance nanofiltration (NF) membranes incorporated with aquaporin Z

“…It was also reported that the size and surface charge of the vesicle had substantial effects on the interaction between the vesicle and the solid surface [26][27]. In addition, the proteoliposome possessed a greater mechanical strength than liposomes and therefore the proteoliposome could nearly maintain its vesicle shape under pressure, while the liposome would fuse into bilayer under the same condition [5,23,28]. In comparison to liposome, the proteoliposome with mutants presented more similar properties as the proteoliposome with AqpZ, only except for the water permeability.…”
