Patent number: 8261662Abstract: Improved actuated probes suitable for scanning probe lithography or microscopy, and especially direct-write nanolithography and method of fabrication thereof. In one embodiment, thermomechanically actuated cantilevers with oxide-sharpened microcast tips are inexpensively fabricated by a process that comprises low-temperature wafer bonding, such as (gold) thermocompressive bonding, eutectic or adhesive bonding. Also provided is a flexcircuit that electrically interconnects the actuated probes to external circuitry and mechanically couples them to the instrument actuator. An improved scanning probe lithography instrument, hardware and software, can be built around the actuated cantilevers and the flexcircuit. Finally, provided is an improved microfluidic circuit to deliver chemical compounds to the tips of (actuated) probes and a fabrication method for tall, high-aspect-ratio tips.Type: GrantFiled: November 8, 2005Date of Patent: September 11, 2012Assignee: Nanolnk, Inc.Inventors: Raymond Roger Shile, Terrisa Duenas, John Edward Bussan, Gregory J.

Patent number: 8235302Abstract: Methods for providing pharmaceutical compositions and objects with identification regions and identification features which are difficult to detect. Microlithography, nanolithography, and stamping methods are used. The identification features can be positive protrusions or negative indentations with respect to the surface. The identification regions can comprise bar codes and holograms. DPN printing or other lithographies such as electron beam lithography, optical lithography, or nanoimprint lithography can be used to prepare stamps, which are then used to prepare the identification features. Redundant patterns can be formed. The invention is useful for counterfeit prevention. An apparatus for stamping the identification features is also described.Type: GrantFiled: April 20, 2005Date of Patent: August 7, 2012Assignee: Nanolnk, Inc.Inventors: Cedric Loiret-Bernal, Linette Demers, Bjoern Rosner, Michael Nelson, Ray Eby, Joseph S.
