Vibrating gel aims to restore voice, help throat cancer victims

Summary:The Who's Roger Daltrey, Aerosmith's Steven Tyler and singer and actress Julie Andrews are backing research into the voice restoring gel by MIT and Harvard professors.

A gel that can vibrate 200 times a second aims to replicate human vocal cords and give throat cancer victims a way to restore their voices.

According to a Bloomberg report, Robert Langer, a researcher at the Massachusetts Institute of Technology, along with Harvard surgeon Steven Zeitels, plan to test this gel next year in a cancer patient. MIT highlighted the voice gel in July.

The experiment is backed by some big voices---The Who's Roger Daltrey, Aerosmith's Steven Tyler and singer and actress Julie Andrews. Daltrey and Tyler were Zeitels patients. About 6 percent of the U.S. population has some kind of voice disorder, according to Sandeep Karajanagi, a former MIT researcher who developed the gel while working as a postdoc in the Langer lab.

Among the key points from the Bloomberg story:

  • The gel is injected into the vocal cords.
  • Once there it acts like a membrane and responds to breath and muscles as real tissue would. Langer rearranged molecules to allow the gel to vibrate at the right speed.
  • The gel has to bond with existing vocal cords and be long lasting. In addition, the elasticity has to be there to respond to muscle contractions.
  • This gel is a form of polyethylene glycol, which is found in some skin creams.
