Nanomotor Based Fabrication and Patterning of Defined Nanostructures
- Detailed Technology Description
- UC San Diego researchers have developed methods and devices for fabricating or patterning nanostructures on surfaces using nanomotors. In one example, catalytic nanowire motors move along predetermined paths to fabricate nano-objects in the presence of the relevant reaction precursors and a catalyst confined to the motor surface. Guided motion of the functionalized nanomotors, enabled by electric or magnetic fields or other means, thus leads to localized reaction in specific locations along the nanomotor path and the ‘writing’ of predetermined nanofeatures. The invention is in proof-of-concept stage but is broad and applicable to different nanomotors and the deposition of a wide range of materials. Relative to DPN, the invention essentially replaces the tip with a nanomotor. With the “pen” thus liberated from the rest of the writing machine and endowed with greater versatility, the invention overcomes DPN’s disadvantages and introduces new capabilities, e.g., simultaneous patterning of multiple lines using several nanomotors and creation of patterns with different heights using on-demand speed control.

Title: Devices and methods for computer-assisted surgery
Usefulness: Devices and methods for computer-assisted surgery
Summary: Device for viewing multiple images for use with a slit lamp, for correlating static pre-surgical images of optical tissues or structures, e.g., the retina, with real-time images or observations obtained with a slit lamp, or other optical viewing device during a surgical procedure to aid in orientation of tissues and devices for performing a surgical procedure. Uses include but are not limited to retinal laser surgeries.
Novelty: Device for viewing multiple images for use with slit lamp or other optical viewing device during surgical procedure has viewing apparatus which simultaneous displays static and real-time digitized images

- *Abstract
-
High-throughput and low-cost techniques for fabrication at sub-50nm scale on wide area substrates are currently a very active and competitive field of cross-disciplinary R&D. Of the recent crop of nanofabrication technologies, dip-pen nanolithography (DPN) is notable for its success in serving the nanofabrication needs of biotechnology, advanced materials, and nano-scale devices. In DPN, molecules in an “ink” are transferred from a coated atomic force microscopy tip to a substrate, forming a pattern as the tip is scanned. DPN however has the disadvantages of slow processing and patterning of small areas and limited parallelization capabilities.
