Biomimetic tongue 3D printed for testing dry mouth therapies

Researchers from the Universities of Leeds and Edinburgh (both UK) have 3D printed synthetic surfaces mimicking the surface of the tongue for testing pharmaceutical properties and dry mouth therapies. Described in ACS Applied Materials & Interfaces, the biomimetic tongue could be used for testing pharmaceutics, therapies for dry mouth and even nutritional technologies. The researchers claim to have replicated the topology, elasticity and ‘wettability’ of a human tongue’s surface, which can reportedly inform the way in which food and saliva reacts with the tongue, mouthfeel, swallowing, nutritional intake and even speech. Due to the complex biological nature of the human…
