Schematic of a functionalized polymer nanoparticle. This type of vehicle can be readily customized to suit the needs of a particular drug delivery application. In particular, the polymer, surface ligands, and encapsulated therapeutic agents can all be modified. This flexibility allows for control over release kinetics, cell targeting, and treatment strategy, respectively. Reproduced, with permission from ref. 62.
