People don't expect diamonds to have anything to do with cancer treatment, but in fact diamond can increase the chances of survival for cancer patients. “Using traditional techniques, it is almost impossible to determine whether cancer treatment is 100% or 99% effective. This difference can have major consequences, because even if there are only a few surviving cancer cells in the body, cancer cells can still spread in the body. Quantum mechanics Diamond sensors will be very sensitive and detect a small number of cancer cells in a large number of healthy cells," said Alexander Huck, associate professor of physics at the Technical University of Denmark. Diamonds are not purchased from jewelers. They are synthetic diamonds with a thin layer of micron on the surface that has the special properties needed to make measurements. This method is based on magnetic biomarkers that can bind to cancer cells but not to healthy cells, a known method principle. The hard part is that although you have created a magnetic difference between the two cells, it requires a very sensitive sensor to detect the magnetic field around each marker. The most famous example of a magnetic sensor is a compass. The guide is sensitive to the Earth's magnetic field and it senses the magnetic field strength between 30 and 40 microtesla. Cancer diagnosis needs to be able to sense the magnetic field strength of dozens of Natsla. The resolution of the diamond sensor is approximately 1 micron. Alexander Huck said, “This is enough for us to distinguish biological cells. We want to be able to detect and isolate individual cancer cells in one million healthy cells.†Why use diamond to detect magnetic fields? Diamond consists of carbon atoms held in a fixed three-dimensional grid. It does not interact with magnetic fields and is therefore not suitable as a sensor. However, Alexander Huck and researchers from Ulm and the University of Leipzig changed the structure to get a defect structure. In each defect structure, the carbon atoms are replaced by nitrogen atoms. This change also creates a number of pores in the crystal lattice of the carbon atoms, causing each atom to disappear, and then heating the diamond to about 800 ° C, which results in pore structure. Move in the middle until they are adjacent to the nitrogen atom. The nitrogen atoms and holes then combine to form a single structure - a NV (nitrogen vacancy) center. The center's role is to absorb light from the green part of the spectrum, and the center emits red light. Each NV center in the diamond also has an electron spin. The spin can be up or down and decide how much red light to emit. In addition to the up and down rotation, it also has periodic changes, just as the earth not only rotates on its axis, but its axis of rotation also changes. The speed and magnitude of these periodic changes are affected by the surrounding magnetic field. In other words, the magnetic field can be studied by measuring the periodic variation of the spin. This is done by illuminating the green light on the center of the defect and detecting how much red light is emitted. The method utilizes a superposition method, a quantum mechanical phenomenon in which particles can be in two states simultaneously. "More specifically, we ensure that the spin of the electrons oscillates up and down at the same time, and the two spins in the center behave differently in the magnetic field." Alexander Huck explained that by detecting the up and down swing variables of the spin, we can determine the magnetic field. Unlike electric fields, when the electric field encounters tissue, blood, and bone, it is significantly affected, and the magnetic field is largely unaffected. 
From the laboratory to the hospital diamond has many advantages in medical treatment. It is a very healthy material that has no health risks when in contact with the body. The team of the Faculty of Physics of the Technical University of Denmark was not the first to propose the use of diamond as a magnetic field sensor. As early as the 1990s, many international organizations have begun to study and make it a reality. However, the interdisciplinary collaboration with the Department of Electrical Engineering at the Technical University of Denmark and with Hvidovre Hospital and Philips gave Alexander Huck and his colleagues a leading position in the medical field. “We can say that this method is closely related to the second stage cancer patients. They have received cancer treatment and the doctor needs to determine how effective the treatment is. However, there is still a long way to go to develop equipment that can be used in hospitals. The next step is to work with colleagues at the Technical University of Denmark to study nanotechnology to design the right equipment.†Alexander Huck hopes to make the first generation of equipment within two years. At the same time, he said, "If we decide to further develop in a new company, then the best time may be when we prepare the first prototype, about two years or so. But there are other options, such as we Existing medical technology companies cooperate. Now we need to consider the scope of use of the device, its application is by no means limited to the field of cancer. When the electron moves from A to B, it will produce a small local magnetic field. If there is enough Sensitive magnetic field sensors allow us to detect many processes in the body. It is a non-invasive technique that does not require surgery or probes. Therefore, this technique is a better choice for critical parts of the body such as the brain or heart.
