[Bio-based pharmaceutical polymers, possibility of their chemical modification and the applicability of modified polymers]

Abstract

Different types of polymers are widely used in biomedical, pharmaceutical and cosmetic purposes. Their applications are curbed, if the polymers can not break down by the body or if the polymer itself is harmful or decompose to harmful material. Authors provide an overview of different types of pharmaceutical polymers of various sources, of the structural characterization and possibilities of their chemical modification and of the classical and instrumental analytical examination methods. The paper deals with the limitations of the use of biopolymers, as well.
