Diamond has excellent chemical inertness, can withstand non-oxidizing acid in a variety of temperature environments, and the composition of the diamond is carbon, which is non-toxic and does not have rejection reaction to the human body. Coupled with its chemical inertness , and no reaction with the blood and other fluids. It turns out that diamond is the ideal medical material.

  NeuroCare and NDI projects, supported by France and Germany as coordinators, funded by the Framework Program (FP7) and Horizon 2020, use nano-diamond as a new medium for interaction with the human body, which is expected to be used in artificial retinal implantation and magnetic resonance imaging (MRI) to achieve an important breakthrough in the field. 

  Among them, NeuroCare project mainly uses the characteristics of nano-diamond or graphene surface, which is dense, nothing can through its surface and diffuse , as the media material between the implant and human nerve tissue. On the one hand to reduce the reaction of the media itself to the nerve tissue, on the other hand, it is also closer to the neuronal cells, so that a higher quality and longer electronic interface can be established between them. At present, for brain interface experiments are usually made of metal materials (such as platinum). However, the metal material for a long time in the human body, its surface is likely to degrade leading to the changes in the nature of electronic exchange. Therefore, the stability of the project is the biggest advantage of nano-diamond technology.

In the field of MRI, the NDI project, supported by the European Research Council (ERC), utilizes the unique optical properties of nano-diamonds to impart scalability to standard MRI scanners on a single cell scale. In the diamond, atomic spin is able to controlled by light and be achieved by laser irradiation to very low temperature that can last for several days. NDI project is the application of this feature of nano-diamond without the need making the body under the premise of cooling to achieve a very low temperature spin.

Researchers from University of California invented a new drug delivery system, the nano-diamond embedded in contact lenses to transport drugs, in order to treat glaucoma. Researchers combine drugs with nano-diamond. When the drug is in contact with lysozyme in tears, it is released and acted on the eye. The researchers said that this treatment is conducive to drug delivery and diamond also makes contact lenses in the process of transporting drugs more durable.

  Diamond, as one of the most special materials in natural world, is featured with the highest hardness, low friction coefficient, high elasticity modulus, high thermal conductivity, high insulation class, wide energy gap, great sound propagation rate and favorable chemical stability，etc. In spite of such unique features, the natural diamond has always been existed in the form of gem, with its variability and rareness sharply limiting its application. CVD Diamond film produced by our company, Luoyang Yuxin Diamond Co., Ltd, integrates such physical and chemical properties with lower cost than natural diamond and applicable to be made into various shapes, thus enjoying extensive application prospect in electronic industry, optical field , medical field and mechanical industry.
