Dip‐Pen Nanolithography Enabled Functional Nanomaterials and Their Applications

Abstract

Abstract Dip‐pen nanolithography (DPN) is a scanning probe lithography technique that can write “inks” directly on a surface with high resolution. The “pen” was initially started from an atomic force microscopy (AFM) tip and later developed to a polydimethylsiloxane (PDMS) tip array to allow for high‐throughput nanofabrication. Over the past two decades, DPN has enabled a wide range of applications from printing arrays of small molecules to fabricating complicated hybrid structures and even integrated systems. In this review, the uses of DPN are focused upon for the synthesis of nanomaterials (NMs) divided by different postprocessing steps after the patterning. The applications of the obtained NMs are also summarized.
