通过测量激光捕获探针的位移，分析了溶液中微米级聚苯乙烯与介质基底之间的表面力。位移量的测量是通过检测由倏逝场照射的探针处的光散射强度来进行的。在不同浓度的电解质三氨基甲烷的实验中，灵敏度为27 fN，范围为5.2 pN。同时还测定了3-氨丙基三乙氧基硅烷在玻璃基片上的表面力分布。
Surface force between a micron-sized polystyrene and dielectric substrate in solution has been analyzed by measuring the displacement of the laser-trapped probe. The amount of displacement is measured by detecting the intensity of light scattering at the probe illuminated by evanescent field. The sensitivity of 27 fN and the range of 5.2 pN have been achieved in the experiment with various concentrations of electrolyte trisaminomethane. The distribution of the surface force of 3-aminopropyltriethoxysilane coated on the glass substrate was also detected.
