        摘要：In this review the relation between biocompatibility of biomaterials and conformation of proteins was expounded.The elaboration includes four propositions as follows:1.The natural conformation of protein is the basis of its biofunctions,2.The sysnergistic effect of peptide chain-lataral group is the driving source for both the foundation of natural conformation and the accomplishment of biofunction of proteins,3.Protein adsorption of biomaterials,4.Relation between biocompatibility of biomaterials and conformation of proteins. It is concluded that one of the best way improving biocompatibility of biomaterials is to maintain the natural conformation of proteins and cells contacted,in that both "Maintaining Normal Conformation" hypothesis and "Chemical Amplification" principle will play a positive role.

        摘要：The application of polymers in the preparation of nanoparticles has been reviewed here.Polymers can be used as dispersion medium or stabilizer for nanoparticles in the sol-gel system. Several methods containing polymers of preparing supermicroparticles have been mentioned. The practicability of polar polymer used as dispersive medium is analyzed,and the universality of preparing nanoparticles by complex transformation is discussed.

        摘要：This review article summarizes the polymer preparation and processing that have been carried out in supercritical carbon dioxide.As will be shown,a number of polymerization reactions, such as the homogeneous freeradical polymerization of flourinated monomers,the dispersion polymerization of methyl methacrylate,the precipitation polymerization of acrylic acid,the inverse emulsion polymerization of acrylamide and the cationic polymerization of isobutyl vinyl ether,can be conducted in supercritical carbon dioxide.Polymerization in supercritical carbon dioxide-swollen polymers can be used to prepare polymer blends with composition gradients. Moreover,supercritical carbon dioxide have been applied in the fractionation of polymers,the formation of porous polymers,and the preparation of polymer submicron fibers and particles.These reports strongly indicate that there is great potential for preparing a wide range of polymers in this enviromentally sound and enexpensive reaction medium.
