Drug Diffusion Testing

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

Controlled-Release Drug Diffusion Tech Brief

Mott's controlled-release drug diffusion studies reduce in vitro test time by more than 90%.

Low-Flow Drug Delivery

Mott can customize delivery devices to meet specific requirements to manage extremely low flows for the release of therapeutic agents to optimize patient outcomes.

Product Specs

Drug Flow Rates

We can customize passive diffusion membranes in a range of porosities and dimensions to meet drug delivery flow rate requirements and concentration over time.  Therapeutic window can be maintained consistently for extended periods.

Flow Accuracy

Achieve consistent zero-order drug release for extended periods at tight dose standard deviation.

Device Hardware

Assemble your flow element into an array of hardware options.


We employ biocompatible titanium and 316L stainless steel, which have been successfully proven for use in implanted devices.  As always, custom alloys and materials are available upon request.

Our Design Capabilities

  • Customizable, ultra-small components used in implantable devices
  • Integrated device concept manufacturing for proof-of-concept trials or transition to production
  • Extensive partner network for new materials
