Can you imagine how to detect a single molecule? Techniques, such as fluorescent spectroscopy and scanning probe microscopy have become available for us to probe single molecules. Described in this article is a simple approach based on atomically thin metallic wires. The interactions of even a single molecule with the wire may cause a large change in the conductance and mechanical properties of the wire and can thus be used to detect single molecules.
