Nanolithography techniques employed today have significant limitations in terms of resolution, speed, and the chemical diversity of the materials that can be patterned on an arbitrary substrate.  Dip-pen nanolithography offers several interesting capabilities, but it requires stringent control over environmental atmosphere and has limitations in substrate choice, patterning speed, and change of topography.  Scanning probe microscopy (SPM) technologies have become increasingly popular due to their potential application in low-cost (and now parallelized) fabrication of nanoscale structures.  Recent experiments have demonstrated that SPM tips can also act as mechanical, thermal, and/or electrical sources to initiate and perform various physical and chemical processes with nanoscale resolution.  [SPIE Newsroom, 6 Aug 2012]
