Encapsulation of Liposomes within pH Responsive Microspheres for Oral Colonic Drug Delivery

Figure 7

Drug release profiles comparing chitosan-coated liposomes (open symbols) with LIMs (black symbols) in simulated GI tract conditions. Each point represents the overall average from three independent experiments ± the standard error of the mean. The figure labels refer to the SEM images which show LIM structure at the various stages throughout the drug release trial.
