  We propose a novel approach to enable the agile manipulation of light- and
dark-seeking particles. Our approach involves introducing a two-curvilinear
perfect optical vortex beam (TC-POVB) generated by superimposing a pair of
curved beams. The TC-POVB exhibits the property of a perfect optical vortex,
which means that its size remains constant regardless of its topological
charge. Additionally, each curve of the TC-POVB can support a distinct orbital
flow density (OFD). This enables the application of torques to produce a dark
channel that satisfies the requirements for particle size and drives the
revolution or rotation motion of the confined dark-seeking particles. To
demonstrate the effectiveness of our approach, we manipulate light- and
dark-seeking particles experimentally, making them perform various curvilinear
trajectories simultaneously, including moving, revolving, and rotating.
