Light exerts pressure on objects: it can grab and hold a tiny particle like tweezers. Now algorithms create surfaces that amplify this grip a hundredfold to catch viruses and assemble quantum components.
🎯 Light can lift and hold a particle in the air, like an invisible tweezer. This phenomenon has been recognized with a Nobel Prize.
🎬 These light traps work like a 'tractor beam' from science fiction, attracting objects without touching them.
