From the clothes and sunglasses you wear to computer hard drives and even cleaning products: nanotechnology - often inspired by nature - plays a major part in the manufacturing of many familiar products. Nanotechnology is an inescapable part of modern everyday life, both on holiday, at work and at home. There are things we've been using for many years which contain nano-sized components, such as the lasers in DVD and CD players. Yet most of the time this technology goes unnoticed. On the whole, people are not very aware of the scope of nanotechnology components around them. However, in the next 20 years, nanotechnology will touch the life of nearly every person on the planet. The potential benefits are mind boggling and potentially brain enhancing. But such as many of the great advancements in human history of innovations, it is not without risk.
