British scientists have developed an innovative diamond-based sensor that could revolutionize how breast cancer spread is tracked. The technology allows for the identification of whether the disease has spread to lymph nodes, offering a safer alternative to current methods using radioactive tracers or fluorescent dyes.

Currently, these techniques have limitations: some patients develop allergic reactions to the dyes, while handling radioactive materials requires additional equipment and protocols that not all hospitals possess. The new diamond sensor, being non-toxic and non-radioactive, aims to overcome these obstacles.

During or before surgery, doctors could inject a magnetic liquid into the tumor. This tracer moves to affected lymph nodes, which can then be located using a sensor with a microscopic diamond tip. Thanks to the unique properties of diamonds, these gemstones can detect minute changes in the magnetic field and accurately pinpoint the lymph nodes to be removed. According to researchers from the University of Warwick, this is the first diamond sensor small enough to be applied in a surgical context. The discovery, published in Physical Review Applied, could optimize the use of magnetic technology already in practice and make detection procedures safer and more effective for patients.
