Drug Delivery Materials

DSM develops and formulates implantable drug delivery systems made of bioresorbable polymers that release precise quantities of therapeutic agents gradually over time. Through strategic alliances and co-development programs, we enable medical device and biopharmaceutical companies to maximize value of their products by incorporating our novel drug delivery materials.
Resorbable materials


We can provide our resorbable materials in various forms, including:

Particles: We formulate microparticles and nanoparticles to meet a variety of delivery challenges. Particle size can be closely controlled with minimal variation. These forms can be delivered to a wide range of sites with broad applicability to different tissue types;

Rods: Our PEA delivery platform can be extruded to combine with difficult or less soluble active agents. The resulting fibers or rods can be injected for sustained local delivery. These forms offer high loading capacities and longer delivery times;

Film, electrospun mats: Our implantable films can deliver across a wide range of timeframes as needed – as can electrospun mats. Direct or laparoscopical implantation can be beneficial for surgical settings;

Coating: DSM resorbable PEA polymers are a good delivery mechanism for drug-eluting stents because they are suitable for coating onto metal and other substrates. Once implanted, the material can elute drug over time while it degrades. The release rate can be tightly controlled, enabling a wide range of functional medical devices from infection control on implants to delivery vehicles associated with long-term structural implants.
