Nano-nose to help identify illnesses

The nano-nose to help identify illnesses is based on a system of six receptors. Each receptor comprises a solution with gold nano particles, and each receptor is provided with a different coating. Nitrogen atoms form special organic molecules, making up the coating of the nano particles.

Different proteins have different characteristics. They attach to different receptors and bind with some receptors more than with others. The scientists wanted to identify those binding properties for different proteins.
