Antimicrobial Activity of Polylactic Acid and Polyethylene Glycol

2 Antimicrobial Activity of Polylactic Acid and Polyethylene Glycol 

It has frequently been reported that the antimicrobial activities of many naturally occurring phenolic compounds in fruits play an important role in their protection against pathogenic microorganisms. It has been suggested that the hy-products of tropical fruit production contain high levels of essential healthy compounds which can be extracted and used for many therapeutic applications of these by-products, phenolic compounds have shown both antimicrobial and antioxidant activities. 

Ritger and Peppas proposed an equation for the release of fruit extract by-products from PLGA NP. This model could be seen as a generalised form of the Fickian diffusion Equation 6.1 [23]
