'Nanoemulsion' gels offer new way to deliver drugs through the skin: Novel materials made with FDA-approved components could deliver large payloads of active ingredients

MIT chemical engineers have devised a new way to create nanoemulsions, very tiny droplets of one liquid suspended within another. They also developed a way to easily convert nanoemulsions to a gel when they reach body temperature, which could be useful for developing materials that can deliver medication when rubbed on skin or injected into the body.
