Many-Body Force and Mobility Measurements in Colloidal Systems
Jason W. Merrill, Sunil K. Sainis, Jerzy Blawzdziewicz +1
We demonstrate a technique for simultaneously measuring each component of the force vectors and mobility tensor of a small collection of colloidal particles based on observing a se…
Many-Body Electrostatic Forces Between Colloidal Particles at Vanishing Ionic Strength
Jason W. Merrill, Sunil K. Sainis, Eric R. Dufresne
Electrostatic forces between small groups of colloidal particles are measured using blinking optical tweezers. When the electrostatic screening length is significantly larger than…
Statistics of Particle Trajectories at Short Time Intervals Reveal fN-Scale Colloidal Forces
Sunil K. Sainis, Vincent Germain, Eric R. Dufresne
We describe and implement a technique for extracting forces from the relaxation of an overdamped thermal system with normal modes. At sufficiently short time intervals, the evoluti…
