  • Patent number: 11234410
    Abstract: A method of making absorbent granules can include mixing activated carbon with a liquid and a binder to form a slurry; applying the slurry to particles of absorbent core material to at least partially coat the particles of the core material with a first distinct layer containing the activated carbon; and applying a clumping agent to the first distinct layer to at least partially coat the first distinct layer with a second distinct layer containing the clumping agent. The absorbent granules can be used as a deodorizer and/or a pet litter, and each of the absorbent granules can include an absorbent core, a first distinct layer containing activated carbon, and a second distinct layer containing a clumping agent such that the first distinct layer is between an outer surface of the absorbent core and an inner surface of the second distinct layer.

  • Patent number: 11221330
    Abstract: The disclosure relates to metal nanoparticle compositions and their methods of formation and use, in particular gold nanoparticles (AuNP) and gold-coated magnetic nanoparticles. Compositions according to the disclosure include aqueous suspensions of metal nanoparticles that are stabilized with one or more carbohydrate capping agents and/or that are functionalized with one or more binding pair members for capture/detection of a target analyte. The nanoparticle suspensions are stable for extended periods and can be functionalized as desired at a later point in time, typically prior to use in an assay for the detection of a target biological analyte. The stable nanoparticle suspension can be formed by the aqueous reduction of oxidized metal precursors at non-acidic pH values in the presence of a carbohydrate-based capping agent such as dextrin or other oligosaccharides.
