ADVERTISEMENT It is a discovery that could revolutionize the fight against cancer. Similarly, British scientists have developed a new way to follow the development of breast cancer in the body. Nevertheless, An original technique because it requires diamonds, they explain in the review Physical Review Applied.
When breast cancer spreads, it often affects the neighboring lymph nodes. For example, Doctors then use radioactive tracers. Meanwhile, fluorescent dyes to make cancer cells visible and identify the degree of metastasis of the disease.
But these approaches have drawbacks: some patients can be allergic to dyes. many hospitals are not equipped to take the additional precautions required during the handling of radioactive materials.
It is by starting when diamonds become weapon against from this observation that the researchers decided to think of a new type of sensor which. according to them, offers a non-toxic and non-radoactive alternative.
According to them. doctors could inject a magnetic tracer liquid into the tumor of a patient before or during a breast cancer operation. The liquid then moves to the lymph nodes, with the metastasized cancer cells.
Optimizing magnetic technology – When diamonds become weapon against
To locate the liquid. identify the nodes to be removed during a surgical operation, doctors would then use a magnetic field sensor with a tiny diamond at its end, the researchers explained. Diamonds have nitrogen vacancy centers, or color centers, which can detect magnetic fields.
These colored centers “Allow the diamond to detect very small variations in the magnetic field. give it a beautiful pink color”said Gavin Morley, one of the study’s authors and professor of physics at the University of Warwick, in a press release.

Gavin Morley’s team managed to reduce the sensor tip to just 10 millimeters. according to them, the first diamond diamond sensor capable of detecting a magnetic tracer liquid while being small enough to be used in surgical operations.
Dr. Stuart Robertson. a surgeon specializing in breast cancer in England, said that magnetic sensors are now used regularly to determine if breast cancer has spread. According to him, this new approach could contribute to “Optimize magnetic technology more”.
