Nanotechnology's next trick could be a real invisibility cloak

Nanotechnology's next trick could be a real invisibility cloak: "Hands up if you haven't dreamt of becoming invisible at times? Researchers have too and are working on proving it's not so impossible.



Alongside some practical applications, such as self-cleaning windows, salads that contain vaccine, and tiny laptop chargers, researchers are working with nanotechnology to make invisibility, or at least a version of it, reality."
