Abstract Background Sensorineural hearing loss a subset of all clinical hearing loss may be correctable through the use of gene therapy. We are testing a delivery system of therapeutics through a 3 cell-layer round window membrane model RWM model that may provide an entry of drugs or genes to the inner ear. We designed an in vitro RWM model similar to the RWM will be referred to throughout the paper as RWM model to determine the feasibility of using superparamagnetic iron oxide Fe3O4 .
