On prilled Nanotubes-in-Microgel Oral Systems for protein delivery.

Newly discovered active macromolecules are highly promising for therapy, but poor bioavailability hinders their oral use. Microencapsulation approaches, such as protein prilling into microspheres, may enable protection from gastrointestinal (GI) enzymatic degradation. This would increase bioavailability mainly for local delivery to GI lumen or mucosa.
