Multifunctional bioerodible/biodegradable polymeric materials

As a part of our continuing interest in the preparation of multifunctional polymeric materials and evaluation of their potential in biomedical and environmental field, a survey on new polymeric systems susceptible to bioerosion and/or biodegradation attack is presented. In particular attention has been focused on the preparation and characterization of the following classes of polymeric materials: 1) hydroxyl‐containing polyesters; 2) functionalized cyclodextrins; 3) hydrophilic polymers containing carboxylic groups; 4) hydrogels for the release of phytodrugs; 5) hybrid polymeric materials; 6) synthetic and semisynthetic polyfunctional polymeric materials for the removal of uremic toxins. A few examples of the use of these polymers in the controlled release of drugs and as coadjuvants in the chronic renal failure treatment will be also presented.
