摘      要：Dynamic control of compact chip-scale contactless manipulation of particles for bioscience applications remains a challenging endeavor,which is restrained by the balance between trapping efficiency and scalable *** offer the implementation of feasible optical tweezers on a planar platform for shaping the exerted optical force by a microscale-integrated *** we design and experimentally demonstrate a highly efficient silicon-based metalens for two-dimensional optical trapping in the *** metalens concept is based on the Pancharatnam–Berry phase,which enables the device for polarization-sensitive particle *** optical trapping setup is capable of adjusting the position of both the metasurface lens and the particle chamber freely in three directions,which offers great freedom for optical trap adjustment and ***-dimensional(2D)particle manipulation is done with a relatively low-numerical-aperture metalens(NA(ML)=0.6).We experimentally demonstrate both 2D polarization-sensitive drag and drop manipulation of polystyrene particles suspended in water and transfer of angular orbital momentum to these particles with a single tailored *** work may open new possibilities for lab-on-a-chip optical trapping for bioscience applications and microscale to nanoscale optical tweezers.
