Direct measurement of optical trapping force gradient on polystyrene microspheres using a carbon nanotube mechanical resonator
Optical tweezers based on optical radiation pressure are widely used to manipulate nanoscale to microscale particles. This study demonstrates direct measurement of the optical force gradient distribution acting on a polystyrene (PS) microsphere using a carbon nanotube (CNT) mechanical resonator, whe...
