Nanotechnology provides us with tools to create functional materials, devices, and systems by controlling materials at the atomic and molecular scales by making use of novel properties and phenomena. Considering that most chemical and biological sensors, as well as many physical sensors, depend on interactions occurring within the nanoscale range, the impact that nanotechnology will have on the sensor world is significant. Nanotechnology-enabled sensors find applications in several fields such as health and safety, medicine, process control and diagnostics. Nanostructured materials will be...

"Gosh, what a rollercoaster of a story: a shining light amid the dark mess of the mental health system" Oliver James

Benjamin Fry's mother died when he was eleven months old and he was cared for by various family friends until, aged two, he went to live with his father, and new step-mother.
