Abstract

We report the synthesis of poly(methacrylic acid)-co-(oleyl methacrylate) with three different amounts of oleyl methacrylate and compare the ability of these polymers with that of poly(methacrylic acid)-co-(cholesteryl methacrylate) (PMAc) to noncovalently anchor liposomes to polymer layers. We subsequently assembled ∼1μm diameter PMAc-based capsosomes, polymer hydrogel capsules that contain up to ∼2000 liposomal subcompartments, and investigate the potential of these carriers to deliver water-insoluble drugs by encapsulating two different antitumor compounds, thiocoraline or paclitaxel, into the liposomes. The viability of lung cancer cells is used to substantiate the cargo concentration-de..
