Exotic Micropumps and Gels Offer Hope for Hearing Disorders

(Scientific American) – Researchers at the Charles Stark Draper Laboratory in Cambridge, Mass., are now testing a tiny polymer matrix that can be loaded with chemical compounds used to treat inner-ear diseases. Whether blended with an existing but limited treatment such as the anesthetic Lidocaine or some as-yet-undiscovered drug, the polymer would be injected into the middle ear and remotely triggered to release its payload into the cochlea, the fluid-filled tubular organ in the inner ear that enables us to hear.
