✦ Synopsis
A direct test of the adhesive strength between particles (2 µm polystyrene latex spheres) in aggregate was carried out to probe the possibility of aggregates being disrupted by convection flows of certain shearing rates. Optical tweezers were used to manipulate individual particles or aggregates for tests in the flow field. The results of our experiment are analyzed to understand how shear flow affects the coagulation process.
