Opis ogólny

Poly (L-lactide) is a semi-crystalline polymer which exhibits strong optical rotation and good mechanical properties. It is mostly used in the synthesis of degradable polymers which are used in orthopaedic devices, in dental applications, as scaffolds for autografted new skin, wound covers, anastomose systems and stents. They are biodegradable since the polyester backbone degrades by simple hydrolysis to form non-toxic compounds.

Zastosowanie

Used in Drug Delivery including coating nanoparticles. Can be end-group functionalizated or used as a macroinitiator/block precursor.

Cechy i korzyści

High initial strength, good strength retention and high amount of crystallinity as much as 70% which in turn is responsible for the very slow degradation rate.

Properties and Applications of Functionalized Graphene Oxide

Professor Aran (Claremont University, USA) thoroughly discusses the engineering of graphene based materials through careful functionalization of graphene oxide, a solution processable form of graphene.

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.

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.
