Drug Diffusion Testing

Mott can conduct your initial drug diffusion feasibility studies to help guide the design criteria for your next generation controlled release drug delivery technology. Built off established surrogate suspensions that serve as a baseline for your unique compounds, our diffusion studies provide you with reliable early assessment of drug diffusion rates and insight into form, fit and function of your device. These studies can shorten in vitro test time and can reduce scope of in vivo modeling, helping you bring your device to market faster.
