A membrane is electrically charged to a polarity. A surface of carbon nanotubes (CNTs) in a solution is caused to acquire a charge of the polarity. The solution is filtered through the membrane. An electromagnetic repulsion between the membrane of the polarity and the CNTs of the polarity causes the CNTs to spontaneously align to form a crystalline structure.

Provided herein is a nanopore structure, which in one aspect is a “carbon nanotube porin”, that comprises a short nanotube with an associated lipid coating. Also disclosed are compositions and methods enabling the preparation of such nanotube/lipid complexes. Further disclosed is a method for therapeutics delivery that involves a drug delivery agent comprising a liposome with a NT loaded with a therapeutic agent, introducing the therapeutic agent into a cell or a tissue or an organism; and subsequent release of the therapeutic agents into a cell.

A method of producing a composite product is provided. The method includes providing a fluidized bed of carbon-based particles in a fluidized bed reactor, providing a catalyst or catalyst precursor in the fluidized bed reactor, providing a carbon source in the fluidized bed reactor for growing carbon nanotubes, growing carbon nanotubes in a carbon nanotube growth zone of the fluidized bed reactor, and collecting a composite product comprising carbon-based particles and carbon nanotubes.

The present disclosure is directed to a method and apparatus for continuous production of composites of carbon nanotubes and electrode active material from decoupled sources. Composites thusly produced may be used as self-standing electrodes without binder or collector. Moreover, the method of the present disclosure may allow more cost-efficient production while simultaneously affording control over nanotube loading and composite thickness.

Provided herein are single wall nanotube constructs to which are convalently linked a plurality of a bifunctional chelator, a therapeutic or a diagnostic radionuclide chelated to each bifunctional chelator and a plurality of morpholino oligonucleotides conjugated to the single wall nanotube. Also provided are single wall nanotube complexes which have the morpholino oligonucleotides on the single wall nanotube constructs hybridized to other morpholino oligonucleotides. The other morpholino oligonucleotides are each conjugated to a therapeutic antibody.

The present disclosure provides a nanotube solution being treated with a molecular additive, a nanotube film having enhanced adhesion property due to the treatment of the molecular additive, and methods for forming the nanotube solution and the nanotube film. The nanotube solution includes a liquid medium, nanotubes in the liquid medium, and a molecular additive in the liquid medium, wherein the molecular additive includes molecules that provide source elements for forming a group IV oxide within the nanotube solution. The molecular additive can introduce silicon (Si) and/or germanium (Ge) in the liquid medium, such that nominal silicon and/or germanium concentrations of the nanotube solution ranges from about 5 ppm to about 60 ppm.

A method of producing a composite product is provided. The method includes providing a fluidized bed of metal oxide particles in a fluidized bed reactor, providing a catalyst or catalyst precursor in the fluidized bed reactor, providing a carbon source in the fluidized bed reactor for growing carbon nanotubes, growing carbon nanotubes in a carbon nanotube growth zone of the fluidized bed reactor, and collecting a composite product comprising metal oxide particles and carbon nanotubes.

The present disclosure is directed to methods for producing a single-walled carbon nanotube in a chemical vapor deposition (CVD) reactor. The methods comprise contacting liquid catalyst droplets and a carbon source in the reactor, and forming a single walled carbon nanotube at the surface of the liquid catalyst droplets.

Provided herein is the two component self-assembly single wall nanotube system and the single wall nanotube construct that is the second component. The two component self-assembly single wall nanotube system has a morpholino oligonucleotide with a targeting moiety followed by a single wall nanotube construct with second morpholino oligonucleotides complementary to the first morpholino oligonucleotides and one or both of a therapeutic or diagnostic payload molecule linked to the single wall nanotube construct.

Devices, compositions, and methods are described which provide a tubular nanostructure or a composite tubular nanostructure targeted to a lipid bilayer membrane. The tubular nanostructure includes a hydrophobic surface region flanked by two hydrophilic surface regions. The tubular nanostructure is configured to interact with a lipid bilayer membrane and form a pore in the lipid bilayer membrane. The tubular nanostructure may be targeted by including at least one ligand configured to bind to one or more cognates on the lipid bilayer membrane of a target cell.
