Optical tweezers ppt
WebSince their introduction a decade ago [1, 2], optical tweezers have become indispensable tools for physical studies of macromolecular [3] and biological [4] systems. Formed by bringing a single laser beam to a tight fo-cus, an optical tweezer exploits optical gradient forces to manipulate micrometer-sized particles. Optical tweezers WebOptical tweezers that use a single-beam laser to trap and manipulate microscopic particles have become a widely used tool in many fields of research, especially in biology, genetics, …
