It can be more than a little frustrating when your glasses fog up — just ask anyone who has worn a face mask over the past two years of the pandemic. Nanotechnology might soon keep your vision clear, however. ETH Zurich researchers have developed a gold nanocoating that heats glass by up to 46F by absorbing a large amount of infrared radiation, keeping your glasses fog-free in many humid conditions. And unlike conventional approaches, which merely spread water around using hydrophilic molecules, this prevents the condensation from even starting.
