Whether it\u2019s enabling MRI scanners to see the way drugs move into cells, or creating secure connections between retinal implants and neurons, diamonds or even tiny fragments of them known as nanodiamonds are lending their glitter to medical research.
\u2018Diamonds or graphene are very dense materials, and therefore nothing diffuses through their surfaces, so there is no contamination of such implants when used to exchange with neural cells electrically,\u2019 said Professor Philippe Bergonzo, coordinator of the NEUROCARE project, which has developed a new type of interface linking medical devices to neural tissues like the retina or the brain based on nanocrystalline diamond and graphene. \u2018The implant needs to be very close to neural tissues to make the difference between two nearby neurons,\u2019 said Prof. Bergonzo, based on France\u2019s Alternative Energies and Atomic Energy Commission. \u2018In the NEUROCARE project \u2026 we were demonstrating that the graphene or diamond materials are able to reduce the tissue reaction, thus to be closer to the neuron cells in order to have a better-quality electrical interface that lasts longer.\u2019 <\/p>\n\n\n\nThe work they are doing means that nanodiamond – and graphene-based brain interfaces are so durable that they could form the basis for long-lasting brain implants that can prevent epileptic fits, and so small that they can be connected directly to a neuron, making retinal implants good enough to allow blind people to read. Today\u2019s experimental brain interfaces use metals such as platinum, but the problem in the long term is the potential degradation of the metal surface within the body, altering the electrical exchange. That\u2019s why nanodiamond technology is so important. It\u2019s the kind of breakthrough that could one day lead to long-term help for locked-in patients, where experimental temporary brain implants aim at enabling them to communicate directly with computers and even operate exoskeletons in institutions such as the Clinatec institute at the Centre Hospitalier Page 1 of 19 Universitaire Grenoble Alpes in France. <\/p>\n\n\n\n
Now the NEUROCARE researchers are looking for a company with the cash to fund formal trials and try to get regulatory approval for it to be used in commercial products, a process which can take around five years. The US This search has led them to look across the Atlantic, even though the original research was funded here in Europe. \u2018In the US companies are a lot more ready to take risks,\u2019 said Prof. Bergonzo. \u2018It\u2019s pretty difficult to find those ambitions in Europe nowadays.\u2019 Innovative companies will also be vital in bringing nanodiamond-based medical imaging technology out of the laboratory and into hospitals and clinics.<\/p>\n\n\n\n
The NDI project, funded by the EU’s European Research Council, is working on the way to use nanodiamonds to enable standard MRI scanners to zoom in on single cells. The project, which runs until the summer, has set up a company to develop the technology and is already collaborating with big high-tech firms such as Germany\u2019s Bosch and France-based Thales. \u2018Once big industry and small startups get involved in this, it will ensure the transfer of technology towards real-world applications,\u2019 said coordinator Professor Fedor Jelezko, from Ulm University in Germany. The technology means that cancer could be detected faster and would help increase the speed of drug development. <\/p>\n\n\n\n
It\u2019s all thanks to the unique properties of nanodiamonds, which are often made by milling down standard diamonds. MRI scanners work by picking up the spin of atoms. However, normally they only pick one nucleus up out of a hundred thousand. The way to improve this is to make the spins extremely cold, which is impossible in a live person. In diamonds, the spin of carbon atoms can be controlled by light, and it can be made very cold using laser irradiation, which lasts for days. \u2018To make the spins very cold, without cooling the sample, the body, we do it with light,\u2019 Prof. Jelezko said. \u2018That\u2019s something where the diamond is a unique material.\u2019 The next step is to take the resolution further and to make the technology user-friendly enough that it can be used in a live setting in medical laboratories.<\/p>\n\n\n\n
\u2018There is a long way to go, but other colleagues and we are working on a path towards this dream,\u2019 he said.
This innovation was made possible by Israel\u2019s continued participation in the official Horizon 2020 fund, managed in Israel by ISERD part of The Israel Innovation Authority (Formerly the Office of the Chief Scientist and MATIMOP). The initiative has taken Israeli R&D to the next level with the help of ground-breaking collaboration between scientists in Israel and Europe, as well as essential funding and support.<\/p>\n\n\n\n
