摘要:
A method of assembling large numbers of nanoscale structures in pre-determined ways using fluids or capillary lithography to control the patterning and arrangement of the individual nanoscale objects and nanostructures formed in accordance with the inventive method are provided. In summary, the current method uses the controlled dispersion and evaporation of fluids to form controlled patterns of nanoscale objects or features anchored on a substrate, such as nanoscale fibers like carbon nanotubes.
摘要:
A method of fabricating optical energy collection and conversion devices using carbon nanotubes (CNTs), and a method of anchoring CNT's into thin polymeric layers is disclosed. The basic method comprises an initial act of surrounding a plurality of substantially aligned nanostructures within at least one fluid layer of substantially uniform thickness such that a first end of the plurality of nanostructures protrudes from the fluid layer. Next, the fluid layer is altered to form an anchoring layer, thereby fastening the nanostructures within the primary anchoring layer with the first ends of the nanostructures protruding from a first surface of the primary anchoring layer. Finally, a portion of the anchoring layer is selectively removed such that a second end of the nanostructures is exposed and protrudes from the anchoring layer. The resulting product is an optically absorbent composite material having aligned nanostructures protruding from both sides of an anchoring layer.

摘要:
The present invention relates to a nano-enhanced device for substance transfer between the device and a tissue. The device comprises a substrate with substantially aligned carbon nanotubes anchored within the substrate, and with at least one end of the carbon nanotubes protruding from the substrate. The protruding nanotube ends may be coated with a drug for delivery of the drug into body tissue. The present invention may be incorporated into an angioplasty catheter balloon or into a patch that is worn on the skin. The carbon nanotubes can be grouped in clusters to effectively form nano-needles which can transfer fluid to or from the subdermal tissue. The nano-needles can be used in conjunction with a sensor to ascertain body fluid information such as pH, glucose level, etc.
摘要:
A fluid transport method and fluid transport device are disclosed. Nanoscale fibers disposed in a patterned configuration allow transport of a fluid in absence of an external power source. The device may include two or more fluid transport components having different fluid transport efficiencies. The components may be separated by additional fluid transport components, to control fluid flow.
