Abstract
Disclosed herein are apparatus and methods for selectively depositing molecular ions on nanoscale substrates such as carbon nanotube arrays using electrospray ionization.
Claims34
A method for selectively depositing one or more ions, comprising:
- providing at least one nanotube in an atmospheric or sub-atmospheric pressure environment, and
- selectively depositing the one or more ions into at least one nanotube, onto at least one nanotube, or both, using an electrospray ion source.
The method of 10, wherein at least a portion of the ions are polymerized to form a polymer matrix.
A method for selectively depositing ions, comprising:
- providing a nanotube assembly, wherein the nanotube assembly comprises one or more end-standing nanotubes linked at one end to a substrate in an atmospheric or sub-atmospheric pressure environment, and
- selectively depositing ions into one or more of the nanotubes in the assembly, onto one or more of the nanotubes in the assembly, or both, using an electrospray ion source.
A system for selectively depositing one or more ions on a substrate, the substrate comprising one or more end-standing nanotubes linked at one end to the substrate, the system comprising:
- at least one electrospray ion source located within a chamber;
- at least one radiation source located within the chamber;
- at least one substrate holder capable of transporting a substrate comprising one or more end-standing nanotubes from a location proximate to at least one of the electrospray sources to a location proximate to the at least one radiation source;
- and
- a controller capable of controlling the spatial orientation of the electrospray ion source relative to the substrate holder to give rise to ions exiting the electrospray ion source being selectively deposited into, onto, or both, at least a portion of the nanotubes.
