Russian Scientists Develop Nanosensors to Find Cancer, HIV and More with Mobile Phone

ucl cancer instituteRussian scientists have developed a nano-sensor to detect cancerous tumours, viral disease markers for HIV, hapatitis and herpes, which appear when the immune system responds to incurable diseases.

The ultracompact nonomechanical sensors help analyze chemical elements and detect bio-dynamics indicating the diseases, said researchers from Moscow Institute of Physics and Technology (MIPT). The sensor can help doctors identify tumour markers, whose presence in the body signals the imminent cancer.

The early detection of cancer and other hard-to-cure diseases will now be easy to diagnose well ahead of the traditional tools. Dmitry Fedyanin and Yury Stebunov, who worked on it with their calculations showed that the new sensor is both highly sensitive and easy to produce in miniature sizes.

The study published in the journal Scientific Reports is more of an optical chip. “Our goal was not only to achieve the high sensitivity of the sensor and make it compact, but also make it scalabile and compatibile with standard microelectronics technologies,” researchers said.

It can also be used in handheld portable devices such as smartphones, wearable electronics and more making it an easy-to-insert device in future smartphones, said the researchers.
