Résumé : |
A large number of different materials are used in a wide range of biomedical applications for which biocompatibility is essential. In order to combine this with the desired bulk structural properties, it is frequently desirable to apply some form of coating or other surface modification.
Factors involved in the interactions between the body and implants are discussed. The process of cell attachment to surfaces is complex and takes place in several stages. Depending on the application, this attachment may be essential or highly undesirable.
Surface modification may be based on physical methods such as flame treatment, corona discharge, UV radiation exposure or laser ablation. Chemical methods include etching, surface oxidation, hydrolysis, chemical grafting and surface coating. Various aspects and applications of these technologies are considered.
Surface modification is a very important aspect of the creation of medically viable polymeric and non-polymeric biomaterials and thus the use of coating techniques in the creation of biomaterials has been growing over recent decades as they can improve the application properties of materials in end uses ranging from catheters to endoprostheses and cardiac valves. |
