For example, PGA sutures can be completely absorbed in the body within 4-6 months. However, limited research based on PGA polymers has been studied in However, for some applications, they are limited by their inferior mechanical properties and unsatisfactory compatibility with cells and tissues. Researchers have extensively investigated the potential of PLGA nanoparticles for target specific and controlled delivery of various micro and macromolecules including drugs, peptides, proteins, monoclonal antibodies, growth factors and DNA in multifarious biomedical applications like neurodegenerative and cardiovascular diseases, inflammatory disorders, cancer and other dreadful health disorders. Background Development of a reliable process for this commercially unavailable monomer led to the discovery of the existence of two glycolide polymorphs one of which exhibits erratic polymerization behavior after exposure to trace amounts of moisture.Polyglycolic acid was converted into fiber by melt extrusion, stretching, and heat setting. Polyglycolic acid (PGA) and poly lactic- co -glycolic acid (PLGA) sutures were introduced in the 1970s as the first synthetic absorbable synthetic sutures and are still used today. There was a significant difference in molecular weight loss and gravimetric weight loss between the blends after 10 weeks in vitro. PGA sutures undergo hydrolysis due to which the sutures are dissolved naturally and get absorbed by the tissues. The immobilization of biological ligands (such as biotin and peptides) onto biodegradable polymer surfaces, including poly (glycolic acid) (PGA) sutures, is complicated by the absence of functional groups on the polymer backbone. Polymers are the most diverse class of biomaterials. Biodegradable polymers have significant potential in biotechnology and bioengineering. The historical development of polyglycolic acid (PGA) and polylactic acid (PLA) polymers and copolymers for use in surgery is set down. in their backbone.
