Nanoworld: from virus to transistors

The Sars-Cov-2 has proven that the minuscules things are as dangerous as the bigger ones (or even more), but the nanoscale is not only a biological one: the invention of transistor, which has led to the biggest technological revolution ever, is the main demonstration of the importance of the nanoworld. Moreover, nanotechnology is here to stay: it will lead to a new revolution capable of changing our lives forever, thanks to the molecular nanomachines. Are we ready to the next nano-revolution?
