(Phys.org) -- Researchers at Johns Hopkins University (JHU) have created biodegradable, ultra tiny, nanosized particles that can easily slip through the body's sticky and viscous mucus secretions to deliver a sustained-release medication cargo. The interdisciplinary team of researchers, led by Justin Hanes of the JHU Center for Nanomedicine, developed the nanoparticles so that they not only penetrate mucus but degrade over time into harmless components. The team believes these nanoparticles have potential for delivering chemotherapeutic agents to tumors in mucus-coated tissues such as the lung and cervix.
