Molecule-sized sensors detect disease from a droplet of blood

Scientists have developed a portable nano-sensor system that can help spot illnesses before people develop symptoms. The technology also enables doctors to closely monitor the performance of drugs, opening a new chapter in personalised medicine.

In 10 seconds? Scientists have created a portable device that uses near-molecule sized sensors to find early warning signs of certain diseases. A droplet of blood is enough to predict prostate cancer, for example, making it possible to initiate early intervention.
