Toxicological Aspects of Polymer Nanoparticles
This chapter describes the effects of some physico-chemical properties of polymer nanoparticles influencing the development of toxicological effects. More particularly, the effect of some parameters that may control the interaction of polymer nanoparticles with the biological environment (such as their composition, size, surface properties, and biodegradability) and, thus, be key factors of their efficacy and toxicity, is discussed. In addition, the chapter also reviews the toxicity results that have been found in the literature regarding the administration of polymer nanoparticles as delivery systems by different ways of administration including intravenous, oral, pulmonary, nasal, and ophthalmic routes.
