Picture MUST credit: Gavin Morley/University of Warwick Diamonds could shine a light on the battle against cancer. Researchers have built a new diamond-based sensor that could be used to better find tumours through tracing magnetic fluid injected in the body. A cancer diagnosis is most problematic when cells from the tumour have spread to other organs known as metastasis. This most often happens through the lymph nodes and the lymphatic draining system. Tests to find whether cancer cells are lodged in the lymph nodes are the gold standard for detecting metastasis and directing the course of treatment. Researchers at the UK's University of Warwick report they have built a new non-toxic and non-radioactive device that uses the unique properties of diamonds to diagnose metastasised breast cancer. This device is ultra-sensitive, handheld and works at long ranges, providing an upgraded solution to a regular challenge that cancer surgeons must cope with. The diamond sensor works by detecting magnetic tracer fluid containing iron oxide nanoparticles which is introduced into the patient during or before breast cancer surgery. The tracer fluid is injected into the tumour and then travels to the lymph nodes alongside metastasised cancer cells. A magnetic field sensor based on a diamond can then locate the tracer fluid and pinpoint the lymph nodes to be surgically removed to stop the cancer spread. Its compact design is achieved by using a tiny 0.5 mm diamond and a small permanent magnet that is attached to the probe head. This eliminates the need for bulky electronics allowing for a handheld versatile tool. Picture supplied by JLPPA
