Nanotech-enabled moisturizer speeds healing of diabetic skin wounds

A new high-tech but simple ointment applied to the skin may one day help diabetic patients heal stubborn and painful ulcers on their feet, Northwestern University researchers report. They are the first to develop a topical gene regulation technology that speeds the healing of ulcers in diabetic animals. The scientists combined spherical nucleic acids with a common commercial moisturizer to create a way to topically knock down a gene known to interfere with wound healing.
