  text: Surface roughness plays an important role in determining the mechanical properties,
    wettability, and self-assembly in colloidal systems. In this work, we develop
    a simple and fast method to produce rough colloidal SU-8 rods, bananas, and spheres,
    via the nanoprecipitation of SU-8 in water. During this process, SU-8 nanospheres
    are absorbed onto the surface of the colloidal SU-8 particles and then cross-linked
    using UV-light. The size of the spherical asperities and the asperity density
    are controlled by the concentration of SU-8 used during the nanoprecipitation
    reaction. Fluorescent labeling of the rough SU-8 colloidal particles allows for
    their confocal imaging, which demonstrates their stability at high packing fractions.
    With these newly developed rough particles, we provide a colloidal model system
    that allows for studies addressing the impact of surface roughness on materials
    composed of anisotropic particles.
