Abstract: The disclosure provides methods, compositions, and kits for enhanced detection of microbes in samples and monitoring of antimicrobial activity in a subject.

Abstract: Described herein are engineered microbe-targeting molecules, microbe-targeting articles, kits comprising the same, and uses thereof. Such microbe-targeting molecules, microbe-targeting articles, or the kits comprising the same can not only bind or capture of a microbe or microbial matter thereof, but they also have improved capability (e.g., enhanced sensitivity or signal intensity) of detecting a microbe or microbial matter. Thus, the microbe-targeting molecules, microbe-targeting articles, and/or the kit described herein can be used in various applications, e.g., but not limited to assays for detection of a microbe or microbial matter, diagnostic and/or therapeutic agents for diagnosis and/or treatment of an infection caused by microbes in a subject or any environmental surface, and/or devices for removal of a microbe or microbial matter from a fluid.

Abstract: Methods, compositions, kits and systems for detecting and/or capturing a target entity in a sample. In particular, the methods, compositions and kits described herein can be used for pre-treatment of target-binding agents with a blocking agent to reduce non-target binding in a complex matrix (e.g., blood). Methods and compositions for detecting and/or capturing a microbe in a test sample, including bodily fluids such as blood and tissues of a subject, food, water, and environmental surfaces are also disclosed.

Abstract: The present invention provides for engineered molecular opsonins that may be used to bind biological pathogens or identify subclasses or specific pathogen species for use in devices and systems for treatment and diagnosis of patients with infectious diseases, blood-borne infections or sepsis. An aspect of the invention provides for mannose-binding lectin (MBL), which is an abundant natural serum protein that is part of the innate immune system. The ability of this protein lectin to bind to surface molecules on virtually all classes of biopathogens (viruses, bacteria, fungi, protozoans) make engineered forms of MBL extremely useful in diagnosing and treating infectious diseases and sepsis.

Abstract: A self-healing, scratch resistant slippery surface that is manufactured by wicking a chemically-inert, high-density liquid coating over a roughened solid surface featuring micro and nanoscale topographies is described. Such a slippery surface shows anti-wetting properties, as well as exhibits significant reduction of adhesion of a broad range of biological materials, including particles in suspension or solution. Specifically, the slippery surfaces can be applied to medical devices and equipment to effectively repel biological materials such as blood, and prevent, reduce, or delay coagulation and surface-mediated clot formation. Moreover, the slippery surfaces can be used to prevent fouling by microorganisms such as bacteria.

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.
