  • Molecular discriminators using carbon nanotubes
    Patent number: 9817002
    Abstract: Methods including contacting, in the solid state, a sample comprising a first organic molecule with a composition comprising: a carbon nanotube, such that an interface forms between the sample and the composition; observing any movement of the interface; and characterizing the first organic molecule based on the observed movement are described.
    Type: Grant
    Filed: August 6, 2012
    Date of Patent: November 14, 2017
    Assignee: UNIVERSITY OF CALCUTTA

  • Configurational chirality based separation
    Patent number: 9726596
    Abstract: A method of determining the relative concentrations of enantiomeric forms of a compound in an enantiomeric mixture includes combining the enantiomeric mixture with carbon nanotubes or graphene to form a carbon-enantiomer mixture, exposing the mixture to a monochromatic polarized light, and analyzing reflected polarized light from the mixture using a differential analyzer.
