By smelling you we can diagnose your disease. its as simple as our nose identify various smells at a time.
based on the same principles as the human nose, one sensor to measure all ~300 chemicals in the breath, and identify a chemical fingerprint based on previously programmed information. That is, during its developmental phase, the chemical sensor is being exposed to chemical combinations that indicate various disorders.
Researchers says that there are approximately 1-5 chemicals per disorder, and that the sensor should be capable of identifying more than one disease at a time, similarly to how the human nose can identify more than one scent at a time.
How the nano sensors works better than existing biomarker tests?
For disease biomarkers such as cancer antigens, the ability to differentiate confidently between a zero result and a trace result is critical.

Conventional biosensors produce a signal that is in proportion to the concentration of target molecules, so at low concentrations they lose sensitivity and become susceptible to interference from other molecules.
The new sensor developed by Molly Stevens and colleagues at Imperial College London and the University of Vigo, Spain, can detect concentrations that are at least 10 times lower than the best existing ultrasensitive tests. "For many diseases, using current technology to look for early signs can be like finding the proverbial needle in a haystack," says Stevens. "Our new test can actually find that needle.".
