  • Coated mesoporous nanoparticles
    Patent number: 11135174
    Abstract: Provided are methods for producing mesoporous nanoparticles that can, once loaded, retain small or large molecules (e.g., molecules having a molecular weight that is less or greater than about 900 Da) until release is desired, upon which time the mesoporous nanoparticles can release the loaded molecule in a controlled manner for a desired period of time, including an extended period of time. Also disclosed are methods for treating a subject comprising administering to the subject a mesoporous nanoparticle according to the present disclosure.
    Type: Grant

  • Method of separating carbon nanotubes
    Publication number: 20100022438
    Abstract: A method of separating carbon nanotubes having substantially the same diameter including the steps of: providing a sample of carbon nanotubes; separating individual nanotubes within the sample, and mixing with a solution comprising fibrous protein fibrils so that at least some individual nanotubes form a complex with the protein fibrils, and separating out those nanotubules which have formed a complex. Preferably the protein is collagen. The separated nanotubes can be used in the fields of electronics, medical and materials science.
