Biomedical applications green polymers

In the case of biomedical applications, metallic impurities coming from the organo-metallic catalysts of ROP may be of concern, because they can accumulate within matrix remnants after degradation [26]. A recent strategy to reduce such problems and to shift polymer synthesis further towards green chemistry is the use of enzymes as catalysts. Kobayashi and Makino [27] published a... 

Green plastics comprise only a very small part (less than 1%) of today s plastics. They do, however, make up a significant part of some specialty, niche markets starch-based loose-fill packaging now constitutes 30% of the loose-fill packaging market. The plastics described here are those currently commercially available, and are limited mainly to those available in the United States. Manufacturers are named only for illustrative purposes the list is not intended to be comprehensive. The plastics materials are described generically, with respect to the major polymer constituent(s) for each generic type there are likely to be many specific formulations. Brief mention is made, at the end, of some materials that have been studied in the laboratory. Biomedical applications are described separately (see Biodegradable Polymers, Medical Applications). 

Aliphatic polyesters like poly(e-caprolactone), poly(butylene succinate), and poly (hydroxyalkanoate)s are widely used. An aromatic polyester of poly(ethylene terephthalate) is much more utilized practically. Poly(lactic acid) (PLA) is an aliphatic polyester and has recently attracted major attention. So far, PLA has been a leading polymer produced from biobased resources. High molecular weight PLA is already produced in various ways and used as a green plastic for electronic products, automobile parts, and in biomedical applications [27-40]. 

NP of the conducting polymer poly(N-ethylaniline) and poly(N-methylaniline) can be prepared using a green approach, i.e., photocatalytic oxidative polymerisation. These polymeric nanomaterials exhibit enhanced antimicrobial activity against various pathogenic bacteria and therefore, find potential applications in biomedical sciences.
