London: A nanosensor can detect cancer from blood sample of a patient before initial symptoms appear, eliminating the need for an invasive biopsy.

The sensor is “10 million times more effective” than traditional tests on patient blood samples, researchers said. It has antibodies that can capture cancerous cells when they come into contact with an affected blood sample, and as a result weigh more. The process causes the cancerous cells to change colour, indicating the presence of a malignant tumour, Priscila Kosaka from the Microelectronic Institute of Madrid said.

 

The sensor may miss only 2 out of 10,000 samples, and can also be used to detect the onset of hepatitis and Alzheimer’s, state run Xinhua news agency reported.

“Currently, there is no method that can detect very low concentrations of molecules,” said Kosaka.
