Johns Hopkins researchers created new biodegradable nanoparticles to efficiently deliver drugs.

Johns Hopkins University researchers have created biodegradable nanosized particles that can easily slip through the body's sticky and viscous mucus secretions to deliver a sustained-release medication cargo.

The researchers say that these nanoparticles, which degrade over time into harmless components, could one day carry life-saving drugs to patients suffering from dozens of health conditions, including diseases of the eye, lung, gut or female reproductive tract.
