Surgical procedures are usually invasive and painful and it could take a long time to fully recover from the incisions surgeons make while performing them. Researchers have created a new technique that can be used to reshape living tissue without making any incisions.

The new “molecular surgery,” which has potentially wide applications, involves the use of only tiny needles, 3D-printed molds, and electric current to reshape living tissue. Without any need for incisions, it does not come with risk of scarring or lengthy recovery times.
