Abstract
A method is described that comprises sorting carbon nanotubes (CNTs) within a fluidic flow for a targeted subset of the CNTs. The sorting comprises attracting at least a portion of the CNTs within the fluidic flow in a direction of increasing intensity of an electric field component of a substantially stationary beam of light. The electric field component has a frequency that is less than one or more resonant frequencies of the CNTs within the portion.
Claims23
An apparatus, comprising:
- a) a first fluidic flow channel to guide a first fluidic flow;
- b) a second fluidic flow channel to guide a second fluidic flow that carries carbon nanotubes (CNTs);
- c) a third fluidic flow channel coupled to said first and second fluidic flow channels, said third fluidic flow channel to guide said first fluidic flow and said second fluid flow along side one another;
- and,
- d) a substantially stationary lens to focus substantially stationary light to a spot within said third fluidic flow channel, said lens positioned to place said spot such that said second fluidic flow flows:
- along or off to a side of said spot and not along or off to another side of said spot that is opposite of said side.
3 more elements
An apparatus, comprising:
- a) fluidic flow channels to run first a second fluidic flows alongside one another;
- and,
- b) one or more lenses and a laser light source arranged to create substantially stationary focused laser light that forms a gradient of electric field intensity within at least one of said fluid flows, said gradient of electric field intensity and the frequency of said laser light's electric field component to cause CNTs, as a consequence of their one or more resonant frequencies relative to said frequency, to leave said first fluidic flow and enter said second fluidic flow.
