Powerful Monitoring Tools

As compared to the analytical and biosensors, nanosensors represent a powerful tool with improved features. These are defined as analytical devices with at least one dimension not greater than 100 nm designed for monitoring the physio-chemical properties in places which are difficult to reach. Nanotubes, nanowires, nanoparticles, and nanocrystals are used to optimize the signal transduction derived by sensing elements in response to exposure to biological and chemical analytes of similar size.
