Electrospun Nanofibers for Drug Delivery Systems

Local delivery of bioactive molecules using an implantable device can decrease the amount of drug dose required as well as non-target site toxicities compared to oral or systemic drug administration.

Poly(Glycerol Sebacate) in Tissue Engineering and Regenerative Medicine

The world of commercial biomaterials has stagnated over the past 30 years as few materials have successfully transitioned from the bench to clinical use. Synthetic aliphatic polyesters have continued to dominate the field of resorbable biomaterials due to their long history and track record of approval with the U.S. Food and Drug Administration (FDA).

Fabrication of Drug-loaded Microparticles Using Hydrogel Technology and Recent Innovation in Automation

Microparticle drug delivery systems have been extensively researched and applied to a wide variety of pharmaceutical and medical applications due to a number of advantages including injectability, local applicability to target tissues and sites, and controlled drug delivery over a given time period.

Biodegradable Polyester Based Nanoparticle Formation by Miniemulsion Technique

Aliphatic polyesters such as polylactide, poly(lactide-co-glycolide) and polycaprolactone, as well as their copolymers, represent a diverse family of synthetic biodegradable polymers that have been widely explored for medical uses and are commercially available.
