Researchers have developed a new and non -radiant device that uses the unique properties of diamonds to diagnose spreading breast cancer, and this device is characterized by a high sensitivity, and it can be carried by hand, which provides an advanced solution to a common challenge facing cancer surgeons.
Diamond sensor works by detecting a magnetic tracking fluid (nanoparticle oxide particles) that are injected during or before breast cancer surgery, this liquid is injected into the tumor and then moves to lymph nodes with widespread cancer cells.
Diamond magnetic magnetic sensor sensor can locate liquid and determine the lymph nodes to be surgically removed to stop the spread of cancer.
The study was conducted by researchers from Warwick University in the United Kingdom, and its results were published in the Physical Review Applied on August 12, and the Yurrick Alert website was written about.
Cancer diagnosis becomes more difficult when tumor cells spread to other organs, this often occurs through the lymph nodes and lymphatic drainage system.
The lymphatic system is one of the components of the circulatory system, and plays an important role in both immune function and excess fluid drainage outside the cells, and the lymph nodes are small tissues that resemble a bean bean, located along the lymph vessels.
Determining tests are if the cancerous cells are stuck in the lymph nodes, the perfect standard for the detection of metastases (a cancerous growth caused by the cancerous cells emanating from the original tumor) and directing the course of treatment.

Alex Newman, co -researcher and doctorate student in the Department of Physics at Warwick University, commented, “There is a real demand for multi -use and non -toxic means to detect cancer. For this new diamond sensor, we were able to reduce the size of the sensor head to only 10 mm, which means that it is the first diamond sensor capable of discovering the magnetic tracking fluid, which is small enough to use the endoscope. It is also very sensitive. Discover part of a hundred of the typical clinical dose of the magnetic tracking fluid. “
Diamond magnetic magnetic sensor sensor can locate liquid and determine the lymph nodes to be surgically removed to stop the spread of cancer.
It achieves its integrated design using a small diamond and a small, permanent magnet fixed to the head of the sensor, and this eliminates the need for huge electronics, allowing the use of a multi -use manual tool.
Professor Javin Morley, chief researcher and leader of the group, of the University of Warwick University, said: “Diamonds can sensitize magnetic fields thanks to the color centers in the diamond, which is called nitrogen vacancy centers. They allow diamonds to discover very slight changes in the magnetic field, which gives diamonds a beautiful pink color,” said Professor Javin Morley, chief researcher and group leader, of the University of Warwick University.
Cancer tracking is not new, but the traditional methods used in hospitals use radioactive techniques that are not available in all hospitals due to the additional reserves needed when dealing with radioactive materials, or simple blue dyes that cause an allergic reaction to one person in every 100.
