タイトル: Measurement of near-wall microparticle motion induced by evanescent-field radiation pressure著者: Kuriyama, Reiko; Inoue, Miyu; Arita, Daiki; Tatsumi, Kazuya抄録: This study confirmed through experimental and theoretical investigations that considering the influences of the neighboring wall on the particle motion due to intermolecular, electrostatic, and hydrodynamic interactions is crucial when studying microparticles’ motion under evanescent-field radiation pressure. The velocity of polystyrene microparticles parallel to the interface was measured in the evanescent field generated at a glass–solution interface. The measured velocity and the estimated radiation force increased with the laser power, decreased rapidly as the incident angle increased from the critical angle and almost overlapped for p- and s-polarizations as reported in previous studies, and scaled with the integrated evanescent intensity over the particle surface. The theoretical estimation of the ...
