Scientists are developing a tiny biosensor that can detect cancer proteins and potential pathogens.

This biosensor is created using a technique similar to that of a gyroscope, akin to the systems used in navigation and airbags. It will be made into a handheld device that enables faster and easier analysis of tissue samples. It is hoped that this device will assist doctors in diagnosing and managing common forms of cancer, providing the most appropriate treatment options.
The device is disc-shaped with a diameter of only 1/10 mm and is coated with special types of DNA or proteins that “trap” cancer-causing agents on its surface. It operates by identifying cancer-causing agents—proteins or other molecules produced by cancer cells.
Professor Calum McNeil, the lead researcher, stated: “Early diagnosis and effective management of cancer is considered key to treating this disease, and we believe this new technique will help achieve that.”
The device can also be easily connected to information sources such as hospital computer systems, the Internet, or mobile phones. It can be developed for applications in other diseases, including those caused by bacteria. Additionally, this technique can be used to detect biological molecules or chemical weapons, allowing it to be integrated into early warning systems to combat terrorist attacks.
