A low-cost portable device has been developed by a team of scientists that may help in the early diagnosis of cancer, just by detecting tumour cells in the blood. Researchers from University in Tarragona (URV) in Spain developed the device, published in Scientific Reports journal, which counts the number of tumour cells in a blood sample in real time. The device can accurately determine a patient's level of health and monitors cancer quickly, cheaply, effectively and non-invasively. It can also assist in the early diagnosis of the disease and monitor tumours more effectively and in a manner that has a less negative effect on patients' bodies. The portable device uses two systems in miniature: a flow system and an optical system. The flow system causes the blood cells to flow in alignment, while the optical system uses two optic fibres (a laser diode and a photodetector) to analyse and count cancerous and noncancerous cells and the ratio between the two reveals how the cancer is progressing...
