Existing medical implants are, in the main, merely tolerated by the surrounding tissue. The Cambridge Centre for Medical Materials (CCMM) at the University of Cambridge Department of Materials Science & Metallurgy researches the next generation of medical materials which interact therapeutically with the body, having bioactive structures which encourage the tissue’s natural function, as well as, for example, providing tailored mechanical support, or releasing drugs at a controlled rate. The group has a strong track record in the fields of skeletal implants, medical prostheses and devices, drug delivery systems, tissue engineering, bioceramics and bioactive coatings and resorbable and stable polymers for implantation.
