Toxicity absorbable/biodegradable devices

Biobased plastics can be used for coatings for drug delivery, bio-absorbable, and other medical devices. Biopolymers are made from non-toxic materials that are compatible with human tissues. PLA, PGA, and PCL are commonly used in biomedical devices (Cheng et al. 2009). The biopolymers are degraded with simple hydrolysis of the ester bonds without the use of enzymes that prevent inflammation. The biodegraded bio-products are eliminated from the body through normal cellular activity and urine. PLA can be used as a bio-absorbable polymer for resorbable plates and screws (Lasprilla et al. 2012). PLA can provide a... [Pg.256]
