摘要：
The surface plasmon resonance phenomenon is widely used in sensing, near-field control, and nonlinear optics. In this paper, the optical near-field generated by the surface plasmon resonance phenomenon is applied to trap yeast cells. The effect of the relative axial distance between the gold film surface and the waist of the focused beam on the trap stiffness is studied. There is a maximized trap stiffness at a specific relative axial distance for trapping yeast cells. The trap stiffness is significantly higher than the value at other locations. This study can be applied to screening of particles with different sizes.
