Nanosensors

Nanosensors convey information about nanoscale materials to the macroscopic world – that is, to a human observer or electrical device. These sensors can be manufactured to detect differences in volume, speed, gravity, electrical charge, chemical composition, pressure, temperature or any number of other physical changes. They may soon be used to detect chemicals such as disease biomarkers, or create nanocircuits with changeable conductivity. You even have nanosensors in your body: Chemical-sensitive neurons in your nose are responsible for your sense of smell.
