Poly lactic-co-glycolic acid synthesis essay

acid (PLGA) is synthesized via melt polycondensation directly from lactic acid and glycolic acid with a feed molar ratio of 7525. PLGA is synthesized by means of ringopening copolymerization of two different monomers, the cyclic dimers of glycolic acid and lactic acid. Polymers can be synthesized as Poly lactic-co-glycolic acid synthesis essay random or block copolymers thereby imparting additional polymer properties.

Sep 01, 2011 2. 1. Poly LacticcoGlycolic Acid (PLGA)Polyester PLGA is a copolymer of poly lactic acid (PLA) and poly glycolic acid (PGA). It is the best defined biomaterial available for drug delivery with respect to design and performance. In past two decades poly lacticcoglycolic acid (PLGA) has been among the most attractive polymeric candidates used to fabricate devices for drug delivery and tissue engineering applications.

PLGA is biocompatible and biodegradable, exhibits a wide range of erosion times, has tunable mechanical properties and most importantly, is a FDA 210 Synthesis and Characterization of Copolymer. Monomer ratios of 7030 and 5050 (D, Llactidegly colide) have been used in acid) (PLGA) particles are the most widelyapplied type of particles due to their biocompatibility and biodegradability. Here, we discuss the preparation of PLGA particles, and various modifications to tailor particles for applications in biological systems.

Feb 28, 2014  1. Introduction. Bone tissue engineering is a research field with many clinical applications, such as bone replacement in the case of orthopaedic defects, bone neoplasia and tumours, pseudoarthrosis treatment, stabilization of spinal segments, as well as in maxillofacial, craniofacial, orthopaedic, reconstructive, trauma, and neck acid) (PLGA) is a common biodegradable polymer that has been utilized in the development of biocompatible devices such as sutures, tissue PLGA microspheres are inherently hydrophobic, and a small amount of surfactant (e.
