Patents by Inventor Frederick Knute Husher

Frederick Knute Husher 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: 20230280578
    Abstract: A shield coating on a microscope slide, and particularly a selective application of a paraffin layer to shield biomaterials and inorganic chemical deposits from microbial attack and oxidation, aid more particularly, an application of a paraffin layer on a microscope slide as an exposure shield over deposited biomaterial reactive targets. The paraffin shield layer blocks the biomaterial and chemical targets from exposure, which may lead to degradation due to oxidation and provides resistance to fungal growth, while using the existing stain processing steps to remove the paraffin from the shield and co-resident tissue section.

  • Publication number: 20110200792
    Abstract: A single layer multi-silane coating construct displays controlled covalent attachment between biological materials and microscope slide substrates. Choice of various silanation reagents and their mix ratios provides control over the overall hydrophilic/hydrophobic surface behavior, attachment site density, and reactive moiety type. Both two-dimensional (2d) and three-dimensional (3d) configurations use the same foundation basics. Improved biological adhesion and fluid flow during subsequent processing is achieved. The 3d configuration offers conformal adhesion for those tissue materials that are not monotonically flat as well as multiple point capture of protein/peptides.
