A new top‐down approach is proposed to form large amounts of anisometric particles. Multicompartment fibers that present different domains composed of silica nanoparticles and larger polystyrene nanoparticles are fabricated by colloid‐electrospinning and are subsequently calcinated and broken. The obtained fibers containing voids are subsequently cut via sonication to yield anisometric particles. It is shown that the majority of the fibers can be broken at the voids.
