Cochlear Implant

There is an unmet medical need for the effective delivery of drugs to the inner ear. Hearing loss not opnly medical, but also social problem. Drug Delivery challenging due to barriers and clearance processes. The controlled delivery with degradable polymers is a rational and promising approach. Specific challenges: small size, biocompatibility, tuned mechanical properties. Innovative and unique delivery systems developed in Halle. Permit personalized medicine.
