Abstract: Provided herein is an antibiotic susceptibility test and related compositions, methods and systems based on detection of a nucleic acid from a target microorganism in a sample in the presence or absence of a lysis treatment of the sample.

Abstract: Provided herein are compositions, systems, kits, and methods for detecting the presence or absence of a target protein in a discrete entity comprising: a) generating a discrete entity (e.g., microdroplet) comprising: i) a first cell that may secrete, or surface express, a target protein, ii) a quenched oligonucleotide probe, iii) first antibody-oligonucleotide conjugate or a particle-oligonucleotide conjugate, and a second antibody-oligonucleotide conjugate that bind the target protein in proximity to each to form an oligonucleotide template structure (OTS), and a nickase enzyme that cleaves the quenched oligonucleotide probe when it is hybridized to the OTS such that a detectable dye (e.g., fluorescent dye) is released and generates a signal; and b) detecting the presence or absence of the signal from the detectable dye.

Abstract: Provided herein are RNA markers and compositions, methods and systems for the related identification and/or uses in methods for detection of antibiotic susceptibility and resistance in a microorganism, and in particular in N. gonorrhoeae.

Abstract: The present invention provides compositions, systems, kits, and methods for analyzing the interaction of T-cells and neoantigen presenting cells (and other cells) via discrete entity (e.g., droplet) microfluids. In certain embodiments, a microfluidic device is used to merge a discrete entity containing a T-cell, and a discrete entity containing a neoantigen presenting cell, at a merger region via a trapping element in order to generate a combined discrete entity. In particular embodiments, at least one thousand of such combined discrete entities are formed in about one second. In some embodiments, whether the receptor on the T-cell sufficiently binds the neoantigen to activate the T-Cell is detected (e.g., via detection of cytokine or granzyme B release). In certain embodiments, provided herein are methods for identifying polyfunctional T-cells or NK-cells, as well as methods of screening for such cells that would be cytotoxic if injected into a subject.

Abstract: Devices and methods for biological sample preparation are provided herein. Components of such devices include a plurality of plungers that can be actuated for metering and/or mixing one or more agents. Methods of manufacturing such devices using 3D printing are also provided.
