Charlie Chandsawangbhuwana 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).

  • Patent number: 10247724
    Abstract: A Petri dish bioreactor can allow a standard Petri dish to be converted to a microscopically observable bioreactor. A bioreactor can be formed by the compression of a device against the edge of a Petri dish thus creating a sealed isolated chamber. One advantage of this conversion is to provide an inexpensive device that can be used for cell culture, observation, transportation, and storage in the laboratory and clinical setting. Further, by creating a sealed bioreactor chamber accessible by ports, the device can reduce cross contamination and allow for the maintenance of a controlled microenvironment within the bioreactor.
    Type: Grant

  • Patent number: 8257940
    Abstract: A diagnostic chewing gum for identifying a risk for diabetes includes a mixture of an enzyme, a conjugated protein of the glucose enzyme, a substrate, and a gum base. The enzyme and the conjugated protein facilitate a conversion of the substrate to produce a detectable signal in the presence of glucose to produce a detectable change in the gum. In use, the gum is chewed, the resulting change in the gum is compared against a chart, and the risk for diabetes is determined from the chart.
