Publication number: 20120085695Abstract: Disclosed is a media (such as a filter media) having one or more carbon nanotube (CNT)-containing layer. Each CNT-containing layer contains high temperature refractory fibers (e.g., staple quartz fibers and/or ceramic refractory fibers) that have melting temperatures greater than about 600° C. and in situ grown CNTs. Substantially all of the in situ grown CNTs have one end thereof associated with the fibers. This results in substantially all of the in situ grown CNTs extending away from substantially all of the fibers. Moreover, substantially all of the in situ grown CNTs are dispersed throughout the fibers. In one embodiment the media also includes one or more supporting layer. Each supporting layer contains high temperature refractory fibers that have melting temperatures greater than about 600° C., optionally bulk refractory fibers, optionally E-glass fibers, and optionally microglass fibers.Type: ApplicationFiled: October 11, 2010Publication date: April 12, 2012Applicants: NanoLab, Inc., Lydall, Inc.Inventors: Abhishek D.

Patent number: 7935517Abstract: A nanostructured molecular delivery vehicle comprising magnetic materials and configured to receive passenger biomolecules. The application of a an appropriate magnetic field having a gradient orients and drives the vehicle into a biological target, which may comprise cells, cell masses, tissue slices, tissues, etc. Under the control of the magnetic field, these vehicles can penetrate cell membranes. Then, the biomolecules carried by the vehicle can be released into the cells to perform their functions. Using this “nanospearing” technique, unprecendented high transfection efficiency has been achieved in several difficult-to-transfect cells. These include, but are not limited to, Bal 17 cells, ex vivo B cells, primary cultured cortical neurons, etc. This method advances the state of the art, providing an improved technique for the introduction of exogenous molecules to cells, with the clinical applications including, but not being limited to, drug delivery, gene therapy, vaccination, etc.Type: GrantFiled: September 22, 2005Date of Patent: May 3, 2011Assignee: NanoLab, Inc.Inventors: Dong Cai, David L.

Patent number: 6950296Abstract: A nanoscale grasping device comprising at least three electrostatically actuated grasping elements. The use of at least three elements, which together define a plane, allows an object to be grasped more accurately, more easily held, and more readily manipulated. The grasping elements preferably comprise conductive nanotubes which are grown at specific points on a substrate (e.g., directly on an electrode), using chemical vapor deposition (“CVD”) techniques, thereby allowing the grasping device to be manufactured with greater control. Different types of electrostatic forces may be used to open or close the grasping tool. Such attractive and repulsive forces can be created through the application of either a constant voltage or an oscillating voltage.Type: GrantFiled: January 25, 2002Date of Patent: September 27, 2005Assignee: NanoLab, Inc.Inventor: David L.

Patent number: 6871528Abstract: A method of producing a branched carbon nanotube (CNT) is disclosed. The branched CNT is used with an atomic force microscope having a cantilever and a tip and that is able to measure a surface of a substrate as well as an undercut feature of the substrate that protrudes from the surface. A catalytic material is deposited onto the tip of the microscope, and the catalytic material is subjected to chemical vapor deposition. This initiates growth of a primary branch of the branched carbon nanotube such that the primary branch extends from the tip. A secondary branch is then introduced to extend from the primary branch and produce the branched carbon nanotube. The primary branch interacts with the surface of the substrate and the secondary branch interacts with the undercut feature.Type: GrantFiled: April 14, 2003Date of Patent: March 29, 2005Assignees: University of South Florida, Boston College, Nanolab, Inc.Inventors: Rudiger Schlaf, Zhifeng F.
