of multiplexing in dip-pen nanolithography with 1D and 2D cantilever arrays is addressed through an inkjet-printing-enabled method for inking pens in an array with different chemical reagents. A new surface-modification strategy directs the ink droplets to the tips of the cantilevers. This method provides control over the inking process and marks a major step towards high-throughput, multiplexed, nanoscale patterning of soft matter.
