Potential Analysis Method Using Photon Force Measurement

Potential Analysis Method Using Photon Force Measurement [Pg.118]

Using this photon force measurement technique, radiation pressure induced by a focused laser beam and an evanescent field [12, 14, 19, 20] was investigated for polymer latexes and metallic particles. Electrostatic forces of charged particles in [Pg.119]

From the changes in the obtained potential profiles, we evaluated the interaction coefficient P and, compared it with the theoretical calculation of p, we also confirmed that the proposed method could evaluate the interaction force without any fitting parameters, which have usually been required in the typical correlation method. [Pg.121]


We introduced the technique for measuring the weak interaction forces acting between two particles using the photon force measurement method. Compared with the previous typically used methods, such as cross-correlation analysis, this technique makes it possible to evaluate the interaction forces without a priori information, such as media viscosity, particle mass and size. In this chapter, we focused especially on the hydrodynamic force as the interaction between particles and measured the interaction force by the potential analysis method when changing the distance between particles. As a result, when the particles were dose to each other, the two-dimensional plots of the kinetic potentials for each particle were distorted in the diagonal direction due to the increase in the interaction force. From the results, we evaluated the interaction coeffidents and confirmed that the dependence of the... [Pg.129]
