  • Patent number: 11919971
    Abstract: This disclosure provides, e.g., methods for coupling Formation of Surface Carboxylates on PES an entity to a solid substrate. The method can comprise treating the with Exposure Time substrate with a plasma, e.g., a CO2 plasma, to increase its reactivity. The entity can be, e.g., a biological polymer that binds a microbe. Substrates produced by these methods can be used in a variety of applications, including hemodialysis and diagnostic assays.

  • Patent number: 11795212
    Abstract: Described herein are engineered microbe-targeting or microbe-binding molecules, kits comprising the same and uses thereof. Some particular embodiments of the microbe-targeting or microbe-binding molecules comprise a carbohydrate recognition domain of mannose-binding lectin, or a fragment thereof, linked to a portion of a Fc region. In some embodiments, the microbe-targeting molecules or microbe-binding molecules can be conjugated to a substrate, e.g., a magnetic microbead, forming a microbe-targeting substrate (e.g., a microbe-targeting magnetic microbead). Such microbe-targeting molecules and/or substrates and the kits comprising the same can bind and/or capture of a microbe and/or microbial matter thereof, and can thus be used in various applications, e.g., diagnosis and/or treatment of an infection caused by microbes such as sepsis in a subject or any environmental surface.

  • Publication number: 20220195017
    Abstract: Described herein are engineered microbe-targeting or microbe-binding molecules, kits comprising the same and uses thereof. The microbe-targeting or microbe-binding molecules can comprise a microbe surface-binding domain linked to a portion of an Fc region. Further, the microbe-targeting molecules can be conjugated to substrate (e.g., a magnetic particle) to form a microbe-targeting substrate. Such microbe-targeting molecules and/or substrates and the kits comprising the same can be used in various applications, such as diagnosis and/or treatment of an infection caused by microbes. Moreover, the microbe-targeting molecules and/or substrates can be easily regenerated after use.
