Polymers with chemically bound bioactive molecules : Synthesis and application to slow drug-delivery

点击翻译按钮获取中文摘要

Slow drug-delivery is an important theme in therapeutic use of steroids and hormones. Some polymer materials have been employed as a matrix but mostly by means of simple physical mixing with drugs, which often leads to unreproducible release of the medicinal molecules. In this project, we have developed new methods to prepare suitable polymers with chemically bonded pendant of bioactive molecules or ions and aimed at creation of bioactive polymer films which are constantly valid for a long pe-riod of time under ambient conditions.
