  text: The bulk synthesis of fluorescent colloidal SU‐8 polymer rods with tunable
    dimensions is described. The colloidal SU‐8 rods are prepared by shearing an emulsion
    of SU‐8 polymer droplets and then exposing the resulting non‐Brownian rods to
    ultrasonic waves, which breaks them into colloidal rods with typical lengths of
    3.5–10 µm and diameters of 0.4–1 µm. The rods are stable in both aqueous and apolar
    solvents, and by varying the composition of apolar solvent mixtures both the difference
    in refractive index and mass density between particles and solvent can be independently
    controlled. Consequently, these colloidal SU‐8 rods can be used in both 3D confocal
    microscopy and optical trapping experiments while carefully tuning the effect
    of gravity. This is demonstrated by using confocal microscopy to image the liquid
    crystalline phases and the isotropic–nematic interface formed by the colloidal
    SU‐8 rods and by optically trapping single rods in water. Finally, the simultaneous
    confocal imaging and optical manipulation of multiple SU‐8 rods in the isotropic
    phase is shown.
