Biomedical materials physical strength

CD polymers (CDPs) are macromolecule derivatives which carry multiple CD units. These units are appended by chemical bonding or physical mixed method. These kinds of polymers not only have the better ability of identification and encapsulation, but also possess good mechanical strength, stability and chemical tenability. The comprehensive function of CD cavity and polymer network could improve the properties of materials. The early investigations always focused on the formation of CDPs by monomers copolymerization. However, several papers showed that the CDs could link to the natural macromolecules to form novel polymers. These polymers were expected to be applied in the functional materials, separation and analysis technology, biomedical engineering, environmental and other high-tech fields [17]. 

In biomedical research, carbon nanomaterials (CNMs) are considered to be the most attractive materials since they possess distinctive physical and chemical properties such as excellent mechanical strength, electrical and thermal conductivity, and optical properties... 

Materials used in biomedical applications are in contact with the body and must therefore satisfy specific requirements they must be nontoxic, biocompatible, and suitable for the specific application, which may require them to have adequate biomechanical properties and physical strucmre. The first-generation biomaterials were designed initially to achieve adequate mechanical strength and a relative state of bioinertness. However, it is impossible to achieve total inertness therefore, second-generation materials are still being developed. These materials are being designed specifically to evoke surface-specific reactions or responses from the biomaterials and particular cells within the body.
