Preparation of modified PDMS membrane with attached dexamethasone-loaded liposomes. (A) Schematic diagram showing the process of preparation of liposome-loaded PDMS membrane. The top surface coated with laminin via the steps of hydroxylation, silanization and laminin crosslinking; the bottom surface loaded with liposomes via hydroxylation, silane-biotinylation, and noncovalent attachment of biotinylated liposomes via streptavidin bridges. (B) Liposome diameter measurement before (left) and after (right) loading with dexamethasone.
