Eduardo de Aquino Ximenes has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Rapid concentration, recovery and detection of pathogens in food samples
    Patent number: 11789018
    Abstract: Methods for rapidly concentrating a food sample for efficient detection of bacteria are disclosed. A microfiltration approach followed by centrifugation was used to concentrate the cells with an enzyme (e.g., a protease) added at the beginning of the process to facilitate more efficient micro-filtering. The enzyme was found to have no significant effect on cell viability.

  • METHOD TO DETECT BACTERIAL ACTIVITY AND PATHOGENICITY WITH BIODYNAMIC SENTINELS
    Publication number: 20190376110
    Abstract: Biodynamic imaging (BDI) performs Doppler spectroscopy of intracellular motion in living samples. The present disclosure describes novel methods and systems to perform: 1) BDI of living 3D tissue culture exposed to bacteria; 2) BDI of living biopsies exposed to bacteria; 3) BDI of infected tissues responding to antibiotics. A novel new element is the use of immortalized cancer cells to generate tissues that act as “biosensors” or “reporters” of bacterial infection, for cells as found directly in aqueous samples and cells that have been concentrated through filtration, centrifugation or a combination while maintaining them in a viable form. Pathogenicity is assessed through the spectral Doppler signatures of the changes in tissue dynamics induced by the bacteria.
