Enhanced optical radiation force can be induced through the resonant scattering field from a single plasmonic nanoparticle or a randomly distributed plasmonic nanoparticle array. In this paper, we utilized the dipole approximation for the Mie scattering field to analyze such radiation force in both far-field and near-field regime. This force can be utilized to develop noninvasive probes for trapping and manipulation of single biological particles. The trapping of single yeast cells is also demonstrated as an application of this approach.
