Optical Trap. Catching a micron-sized particle is challenging. To get the job done, two laser beams come in handy. Acting like tweezers, they can trap, secure, and charge a solitary particle.

A new study led by Vinod M. Menon and his group at the City College of New York shows that trapping light inside magnetic materials may dramatically enhance their intrinsic properties. Strong optical ...
