his paper explains a simple, inexpensive method for the fabrication of non-spherical polymeric particles. This method involves
the use of a mechanical rubbing-assisted colloidal crystal to generate a substrate with an array of dimples on its surface, followed
by selectively depositing a polymer into the dimples. As a proof-of-concept experiment, we demonstrated the fabrication of poly
(ε-caprolactone) (PCL) particles with non-spherical shape. The shape of the polymer particles could be controlled from disk to
hemisphere by changing the surface structure and property of the substrate and the concentration of the polymer solution. When
functional components including drug molecules and inorganic NPs were used together with the polymer, we could easily obtain the
non-spherical particles loaded with the components. In addtion, non-spherical particles with a hollow structure were formed with
the use of immiscible polymer blend consisting of PCL and poly(ethylene oxide) (PEO).
