A method of fabricating a graphene oxide material in which oxidation is confined within the graphene layer and that possesses a desired band gap is provided. The method allows specific band gap values to be developed. Additionally, the use of masks is consistent with the method, so intricate configurations can be achieved. The resulting graphene oxide material is thus completely customizable and can be adapted to a plethora of useful engineering applications.

Efficient methods for producing a superhydrophobic carbon nanotube (CNT) array are set forth. The methods comprise providing a vertically aligned CNT array and performing vacuum pyrolysis on the CNT array to produce a superhydrophobic CNT array. These methods have several advantages over the prior art, such as operational simplicity and efficiency.

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.
