In 2013, a scalpel-shaped invention revolutionised cancer surgery . Scientists at Imperial College London surprised the medical community with a knife that detects cancer cells as it passes over a patient's skin.
The scalpel is connected to a spectrometer that differentiates healthy and diseased cells. The tip of the iKnife is heated and the smoke that it gives off when it touches the skin is recognized by the machine. And this is how it distinguishes one cell from another.
This way, the surgeon can easily know which tissue to cut when removing a tumor. This also prevents the disease from recurring .
During its first interventions, this brazil phone data medical device had a 100% success rate after being used in 91 hospitals.

Contact lenses that measure glucose
Diabetics now have a smart solution to measure their glucose levels. In fact, they don't even have to do it themselves because these smart contact lenses tell them the amount in their blood.
This medical device was invented a couple of years ago at the University of Ulsan in South Korea. Tears are the key to this invention . When the user sheds them, the built-in sensor can detect whether glucose levels have risen. If so, it alerts a nanoscreen that there is a risk. Then, an LED light is responsible for telling the user if there have been alterations (it turns off if there have been any).
