Nanotechnology could be the key to future scientific and engineering breakthroughs, space travel and kickstarting a new industrial revolution. But what exactly is it?In this accessible and concise primer, Rahul Rao takes the reader on a journey to the hidden world of the nano realm. This world exists is invisible to the human eye but, without it, life as we know it simply wouldn't exist. Nanotechnology is the craft of editing, manipulating and shaping this parallel world in ways that can have profound impacts on a huge scale. Celebrating the power and potential of the small things, this book looks at a diverse range of examples of nanotechnology including super-strength carbon nanotubes, speciality nanoparticles and biological nanomachinery. It explains the science behind these breakthroughs and offers a tantalising glimpse at what may await us in the world of tomorrow.
