• printing stamps was fabricated by standard photolithography [14][38][39]. Briefly, a positive resist (AZ1518) was spin-coated to a height of 2.1 ± 0.1 μm onto a silicon wafer, exposed through a sub-micrometer resolution chrome mask and developed. After overnight silanization, poly(dimethylsiloxane) (PDMS
