摘要:
Mucus penetrating particles (MPPs) include one or more core polymers one or more therapeutic prophylactic and/or diagnostic agents and one or more surface modifying agents. The surface modifying agents coat the surface of the particle in a sufficient density to enhance the diffusion of the modified nanoparticles throughout the mucosa relative to equivalent nanoparticles that are not surface modified. Nanoparticles can be sufficiently densely coated with poly(ethylene glycol) (PEG) with a molecular weight of from 10 kD to 40 kD or greater coated with a surface density from about 0.1 to about 100 molecules/100 nm2 preferably from about 0.5 to about 50 molecules/100 nm2 more preferably from about 0.9 to about 45 molecules/100 nm2.
