Roadmap for optical tweezers

Abstract Optical tweezers are tools made of light that enable contactless pushing, trapping, and manipulation objects, ranging from atoms to space sails. Since the pioneering work by Arthur Ashkin in 1970s, optical have evolved into sophisticated instruments been employed a broad range applications life sciences, physics, engineering. These include accurate force torque measurement at femtonewton level, microrheology complex fluids, single micro- nano-particle spectroscopy, single-cell analysis, statistical-physics experiments. This roadmap provides insights current investigations involving forces their theoretical foundations designs setups. It also offers perspectives for wide research fields, biophysics exploration.
