Latest Patents

One of his latest patents is titled "Methods for identifying species or Shigella and E. coli using operon sequence analysis." This patent describes a method for comparing the variable reactivity of multiple, differentially mutated copies of 16S subsequences found in various ribosomal RNA operons of a single bacterial cell. The application of this method is crucial for distinguishing between closely related organisms, such as the genera Escherichia and Shigella, and between species of Shigella using nucleic acid probes.

Another significant patent is the "Optical fiber evanescent field excited fluorosensor and method of manufacture." This invention involves a tapered optical fiber that has a material coated on it for chemical bonding with fluorophores. When the fluorophores couple with the material, the evanescent radiation generated by the fibers causes the fluorophores to fluoresce, which is then coupled back into the fiber.
