Review of Recent Development on Preparation, Properties, and Applications of Cellulose-Based Functional Materials

Schematic of the paper-abetted lipid hydration in aqueous solutions method. The steps for the method are as follows: (a) Deposit a solution of lipids in chloroform onto the paper, allow the solvent to evaporate, and coat the cellulose fibers with a dry lipid film. (b) Place the dry lipid-coated paper into a desired aqueous solvent and incubate it for 30−120 min. Sandwiching the paper between polystyrene well inserts and elastic bands offers a convenient means of immobilizing the lipid-coated paper in a buffer-containing chamber. (c) Following a growth period, flow an extraction buffer through the paper to detach the liposomes into the bulk. Alternatively, use a cut pipet tip to aspirate the liposomes from the surface of the paper. Reprinted from [8].
