Five-membered unsubstituted lactone, y-butyro-lactone (y-BL), is not polymerized by conventional chemical catalysts. However, oligomer formation from y-BL was observed by using PPL or Pseudomonas sp. lipase as catalyst.1523 157 d-Valerolactone (<3-VL, six-membered) was polymerized by various lipases of different origin to give the polymer with Mn of several thousands.148 Another six-membered lactone, l,4-dioxan-2-one, was polymerized by Candida antarctica lipase (lipase CA) to give the polymer with Mw higher than 4 x 104.158 The resulting polymer is expected as a metal-free polymeric material for medical applications.

Hopefully, the foregoing brief lists provides some insight into the potential of protein-based polymers in the marketplace. There simply are no comparable soft materials for medical applications. Certain of the above-listed advantages are discussed in more detail immediately below and throughout this chapter. 

Nanofiber of biodegradable plastics such as P(3HB) and its copolymers is an attractive material for medical applications. We succeeded in obtaining weU-organized nanofibers by an eletrospinning technique from dilute polymer solution. The fiber morphology and the crystalline structure of nanofibers are also reported in this chapter. In the last section, enzymatic and in vivo degradation of both monofilaments and nanofibers are presented. 

The application of radiation and gas discharge processing to synthesize or modify polymeric materials for medical applications continues to increase in interest and diversity around the world. Incorporation of biologically active molecules is an important additional processing step which can open up many new and exciting medical applications for diagnosis and therapy.

Chitosan, a biopolymer, has attracted considerable attention due to its many physical and chemical properties and due to its many applications inclnding its usage as a material for medical applications, such as artificial skin and immnnosnppressarrt. In addition, resins derived from chitosan have been synthesized and characterized. The chelation and sorption properties of these chitosan-based polymers towards heavy metal ions in aqueous solutions have been investigated by several research groups. Therefore, the aim of this article will be to shed some light on some of these chitosan-derived resins and their application to sorption of heavy metal ions and some anions.
