We live in the age of nanotechnology. We have lived in the era of nanotechnology for more than ten years. Don't know? Don't believe it? Doubt it? The purpose of this book is to give knowledge, instill faith, dispel doubts. Let's look at nanotechnology with an open mind and see that they are nothing more than a new synthetic science-intensive discipline, within which the long-awaited unification of physical, chemical and biological knowledge took place. We look into the world around us, in ourselves - and we will see many nano-objects that make up the material basis of being.
