Scientists at Warwick University in the United Kingdom have introduced an important innovation in the field of medicine. This was reported by Zamin.uz.
They have developed a new method for detecting cancer metastases using a compact and portable diamond-based sensor. This research was published in the journal “Physical Review Applied.”
Cancer cells spread to other organs through the lymphatic system without damaging only the primary tumor. Therefore, determining the condition of lymph nodes is very important, as it helps doctors to correctly determine the treatment approach.
Currently, radioactive markers or special dyes are used in this process. However, radiopharmaceutical substances are not available in every clinic, and dyes can cause allergic reactions in some patients.
The new sensor device from Warwick University physicists offers a different approach. This sensor operates based on NV centers, which consist of nitrogen atoms and defects in the crystal lattice, capable of detecting the smallest changes in magnetic fields.
The device reacts to a special magnetic fluid containing iron oxide nanoparticles. Using this technology, it is possible to accurately detect the spread of the tumor to lymph nodes and precisely remove these nodes during surgery.
According to the study’s author, Alex Newman, the sensor’s main part is compacted to only 10 millimeters, making it very convenient for use in endoscopy and laparoscopy procedures. The device uses a micro-diamond of 0.5 cubic millimeters and a small permanent magnet, so no additional large electronics are required.
For this reason, doctors highly appreciate the new technology. Stuart Robertson, a surgeon at Coventry and Warwick Hospital, emphasized that he regularly uses magnetic navigation methods in breast cancer treatment, which are more effective than traditional methods.
Collaboration with Warwick University to further develop the technology is important. Experts believe that in the future, this sensor can also be used to detect various tumors in the lungs, liver, intestines, and esophagus.
This marks the beginning of a new era in cancer detection and treatment.
