Web12 apr. 2024 · Liposomes were produced by multiple sequential extrusion steps using a mini extruder (Northern Lipids, Burnaby, BC, Canada) through polycarbonate membranes (Nuclepore, Pleasanton, CA, USA) with final filters. The liposomes were filtered through a 0.22-μm nylon filter and stored at 4°C. Web11 jan. 2003 · The formation of membrane tubes (or tethers), which is a crucial event in many biological processes, is intrinsically a dynamic process. In this paper, we discuss both theoretically and experimentally the dynamical laws that govern extrusion and retraction of tubes extracted from lipid vesicles at high speed and under strong flows.
WebLipids serve as excellent excipients for drug products. Solid lipid microparticles ... We use microfluidic flow extrusion of the solution to generate uniform drug-loaded SLMs, substantially enhancing monodispersity. This method generalises across three drugs-ibuprofen, 5-methyl-2-[(2-nitrophenyl)amino]-3-thiophenecarbonitrile ... WebONdrugDelivery
WebLipids play a significant role as a barrier to sustain the release of drugs and biocompatible nature of lipids increases their acceptability by the human body. Further, lipids provide vast opportunities of altering pharmacokinetics of the active ingredients by … WebLipids in the gel-liquid phase are very hard to be extruded effectively at low pressures because the interfacial rheological behavior of the lipid membrane is temperature …
WebA new scalable liposome production system is presented, which is based on the ethanol injection technique. The system permits liposome manufacture regardless of production scale, as scale is determined only by free disposable vessel volumes. Once the parameters are defined, an easy scale up can be performed by just changing the process vessels.
