Latest Patents

One of her latest patents is titled "Half-frequency spectral signatures." This technique determines whether a fluorescent material exhibits directionally dependent properties, such as anisotropy or chirality. The method involves illuminating the particle at its excitation wavelength to stimulate fluorescent emission at both full-frequency and half-frequency wavelengths. The ratio of the full-frequency signal strength to the half-frequency signal strength indicates the sample's directionally dependent property. This half-frequency spectral analysis can be utilized to sort anisotropic particles suspended in fluid flowing through a flow cytometer. For example, this technique may be employed to separate racemic mixtures of chiral enantiomers of cells, pharmaceutical compounds, and other samples.

Another notable patent is "Configurational chirality based separation." This method determines the relative concentrations of enantiomeric forms of a compound in an enantiomeric mixture. It involves combining the enantiomeric mixture with carbon nanotubes or graphene to form a carbon-enantiomer mixture. The mixture is then exposed to monochromatic polarized light, and the reflected polarized light is analyzed using a differential analyzer.
