    Abstract

    rogress made in the last two decades in chemical vapour deposition
    technology has enabled the production of inexpensive, high-quality
    coatings made from diamond to become a scientific and commercial
    reality. Two properties of diamond make it a highly desirable candidate
    material for biomedical applications: first, it is bioinert, meaning
    that there is minimal immune response when diamond is implanted into the
    body, and second, its electrical conductivity can be altered in a
    controlled manner, from insulating to near-metallic. In vitro, diamond can be used as a substrate upon which a range of biological cells can be cultured. In vivo,
    diamond thin films have been proposed as coatings for implants and
    prostheses. Here, we review a large body of data regarding the use of
    diamond substrates for in vitro cell culture. We also detail
    more recent work exploring diamond-coated implants with the main targets
    being bone and neural tissue. We conclude that diamond emerges as one
    of the major new biomaterials of the twenty-first century that could
    shape the way medical treatment will be performed, especially when
    invasive procedures are required.
