To prepare the immunologically modified nanotubes, carbon nanotubes are dissolved in a solution of glycated chitosan, an immunostimulant, hence using glycated chitosan as a surfactant for rendering the aqueous solution of nanotubes stable. The compound can be used for treatment of cancer. The method includes steps of intratumorally administering immunologically modified nanotubes and administering laser irradiation of the target tumor. The nanotube serves as a carrier to deliver immunoadjuvants to the tumor cells and serves as a light-absorbing agent in a cell body of a tumor in a host.Type: ApplicationFiled: February 28, 2011Publication date: August 30, 2012Inventor: WEI R.

Patent number: 8246886Abstract: A method and system for aligning nanotubes within an extensible structure such as a yarn or non-woven sheet. The method includes providing an extensible structure having non-aligned nanotubes, adding a chemical mixture to the extensible structure so as to wet the extensible structure, and stretching the extensible structure so as to substantially align the nanotubes within the extensible structure. The system can include opposing rollers around which an extensible structure may be wrapped, mechanisms to rotate the rollers independently or away from one another as they rotate to stretch the extensible structure, and a reservoir from which a chemical mixture may be dispensed to wet the extensible structure to help in the stretching process.Type: GrantFiled: July 9, 2008Date of Patent: August 21, 2012Assignee: Nanocomp Technologies, Inc.Inventors: David S.
