Patents by Inventor Karen Maxwell

Karen Maxwell 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).

  • Publication number: 20230167426
    Abstract: The present invention is related to the field of CRISPR-Cas9 gene editing platforms. In particular, the present invention has identified Type II-C Cas9 anti-CRISPR (Acr) inhibitors that control Cas9 gene editing activity. Co-administration of such Acr inhibitors may provide an advantageous adjunct in permitting safe and practical biological therapeutics through spatial or temporal control of Cas9 activity; controlling Cas9-based gene drives in wild populations to reduce the ecological consequences of such forced inheritance schemes; and contributing to general research into various biotechnological, agricultural, and medical applications of gene editing technologies.

  • Publication number: 20210132001
    Abstract: Disclosed are methods and systems for the detection of bacteria in a sample. The methods comprises contacting the sample with an antibacterial agent and a bacteria identification sensor, and involves the permeabilization of the bacteria by the antibacterial agent, and the subsequent detection of an efflux of potassium ions using a bacteria identification sensor comprising a potassium-sensitive ISFET. Also disclosed are bacteria identification sensor comprising a potassium-sensitive ISFET useful in the practice of the disclosed methods.
