Steven W. Metzger 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: 9434937
    Abstract: Methods and systems for purifying cells and/or viruses are provided. The sample is added to a well disposed in a medium. A potential is applied across the medium to cause the contaminants to enter one or more walls of the well, and retain the cells and/or viruses in the well. The cells and/or viruses can be removed from the well, and optionally adhered or fixed to a surface, or detected. In one embodiment, the cells and/or viruses may be retained in the well by embedding in the medium. The medium including the embedded cells and/or viruses may be excised or otherwise removed and transferred to a glass slide or other solid surface.
    Type: Grant

  • Publication number: 20150225762
    Abstract: Generally provided are methods for rapid culture of microorganisms in a sample, including methods for growth and recovery of live microbial cells directly from a sample. Various features include enabling growth of microorganisms in a sample along with a reduction of sample debris that may interfere with microorganism detection, and reduction in toxicities that may inhibit microorganism growth. Further methods for selectively degrading non-viable microbial cells, are provided, for enhanced detection of viable microbial cells following a growth period.

  • Patent number: 8895255
    Abstract: The present invention relates to moving microorganisms to a surface, where they are grown in the presence and absence of antimicrobials, and by monitoring the growth of the microorganisms over time in the two conditions, their susceptibility to the antimicrobials can be determined. The microorganisms can be moved to the surface through electrophoresis, centrifugation or filtration. When the movement involves electrophoresis, the presence of oxidizing and reducing reagents lowers the voltage at which electrophoretic force can be generated and allows a broader range of means by which the target can be detected. Monitoring can comprise optical detection, and most conveniently includes the detection of individual microorganisms. The microorganisms can be stained in order to give information about their response to antimicrobials.

  • Publication number: 20120288717
    Abstract: Compositions and methods of preparing functional thin films or surface coatings with low non-specific binding are described. The thin films contain specified functional groups and non-specific binding repellant components. The thin films are either covalently bound to or passively adsorbed to various solid substrates. The specified functional group provides specified activity for the thin film modified solid surfaces and non-specific binding repellant components significantly reduce the non-specific binding to the thin film modified solid surfaces. Non-specific binding repellant components do not affect specified functional group's activity in the thin films. In these methods, specified functional groups are anchored to the solid substrates through a spacer.
