SWARNALATHA SWAMINATHAN 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: 20210038753
    Abstract: A self-contained biological sterilization indicator is provided. The self-contained biological sterilization indicator includes an outer container having at least one liquid-impermeable wall and an interior volume; a sealed, openable, liquid-impermeable inner container enclosing a predetermined volume of an aqueous medium; a dry coating that comprises i) a plurality of viable test microorganisms useful to detect exposure to an oxidative sterilant and ii) an effective amount of a sterilant-resistance modulator; and a pathway that permits vapor communication between the interior volume and an atmosphere outside the outer container. The inner container and the dry coating are disposed in the interior volume. The modulator comprises an amino acid. The effective amount causes an increase in sensitivity of the test microorganisms to the oxidative sterilant relative to an otherwise-identical dry coating that lacks the effective amount.

  • Publication number: 20170252475
    Abstract: An article and method are provided for assessing the efficacy of a sterilization process. The article comprises an outer container having an interior volume; a dry source of measurable biological activity disposed in the interior volume; and an effective amount of a dry agent for neutralizing a sterilant compound; wherein both the source of measurable biological activity and the agent are in vapor communication with an environment outside the outer container. The method comprises exposing the article to a first sterilant and, optionally, a second sterilant for a period of time and detecting the measurable biological activity.

  • Publication number: 20160289732
    Abstract: The present disclosure provides a monitoring device comprising a test composition, a test element comprising a test portion to which the test composition is releasably adhered, a detection reagent, and a container comprising a first end with an opening and a second end opposite the first end. The test composition comprises a predetermined quantity of tracer analyte. The container is configured to receive the test portion and configured to be operationally coupled to an analytical instrument. The tracer analyte and the detection reagent each are capable of participating in one or more chemical reaction that results in the formation of a detectable product. A method of using the monitoring device to assess the efficacy of a washing process is also provided.
