Simple Method for the Direct Measurement of Cohesive Forces Between Microscopic Particles
Johnathan Hoggarth, Kari Dalnoki-Veress
We present a simple and inexpensive method for measuring weak cohesive interactions. This technique is applied to the specific case of oil droplets with a depletion interaction, di…
