- University of Warwick scientists have developed a diamond-based sensor designed to trace tiny magnetic particles injected into the body.
- This handheld device offers a non-toxic alternative to radioactive tracers and dyes currently used to detect the spread of cancer cells to lymph nodes.
- The sensor is highly sensitive, capable of detecting just one hundredth of the typical magnetic tracer fluid dose, and is small enough for endoscopic and keyhole surgery.
- Its design incorporates a half-cubic millimetre diamond with nitrogen vacancy centres, allowing for compact, handheld use without bulky electronics.
- Researchers believe the technology could improve cancer detection for various tumour types and has potential applications beyond medicine, including in spacecraft and fusion power.
