We present new findings on how the presence of particles alters the pinch-off dynamics of a
liquid bridge. For moderate concentrations, suspensions initially behave as a viscous liquid
with dynamics determined by the bulk viscosity of the suspension. Close to breakup,
however, the filament loses its homogeneous shape and localised accelerated breakup is
observed. This paper focuses on quantifying these final thinning dynamics for different sized
particles with radii between 3 μm and 20 μm in a Newtonian matrix with volume fractions …
