Abstract: Pressure control in fluidic systems is generally described. In some cases, a system comprises a fluid-permeable (e.g., liquid-permeable) medium and a pressure regulator. The medium and the pressure regulator can be positioned between a first fluidic channel and a second fluidic channel. The medium is arranged, in certain cases, such that fluid (e.g., liquid) can be transported from the first fluidic channel, through the medium, and into the second fluidic channel. In certain cases, when a first pressure within the first fluidic channel is below a sum of the permeability pressure differential of the medium with respect to the fluid and a second pressure within the second fluidic channel, the fluid is substantially prevented from being transported through an outlet of the first fluidic channel.

Abstract: Gene editing can be performed by introducing gene-editing components into a cell by mechanical cell disruption. Related apparatus, systems, techniques, and articles are also described. The methods and systems of the invention solve the problem of intracellular delivery of gene editing components and gene editing complexes to target cells. The results described herein indicate that delivery of gene editing components, e.g., protein, ribonucleic acid (RNA), and deoxyribonucleic acid (DNA), by mechanical disruption of cell membranes leads to successful gene editing. Because intracellular delivery of gene editing materials is a current challenge, the methods provide a robust mechanism to engineer target cells without the use of potentially harmful viral vectors or electric fields.

Abstract: A portable, microfluidic blood plasma separation device is presented featuring a constriction-expansion design, which can produce up to about 100% purity for undiluted blood at least about 9% yield. This level of purity represents an improvement of at least one order of magnitude with increased yield compared to that achieved previously using passive separation. The system features high flow rates, 5-30 ?L/min plasma collection, with minimal clogging and biofouling. The simple, portable blood plasma separation design can be hand-driven and can easily be incorporated with microfluidic or laboratory scale diagnostic assays. The separation system can be used in conjunction with portable analyte detection tests at concentrations well below clinical relevancy for undiluted whole blood.

Abstract: Methods and system for solid phase peptide synthesis are provided. Solid phase peptide synthesis is a known process in which amino acid residues are added to peptides that have been immobilized on a solid support. New amino acid residues are added via a coupling reaction between an activated amino acid and an amino acid residue of the immobilized peptide. Amino acids may be activated using, e.g., a base and an activating agent. Certain inventive concepts, described herein, relate to methods and systems for the activation of amino acids. These systems and methods may allow for fewer side reactions and a higher yield compared to conventional activation techniques as well as the customization of the coupling reaction on a residue-by-residue basis without the need for costly and/or complex processes.

Abstract: Pressure control in fluidic systems is generally described. New trends in chemical synthesis involve the use of continuous reaction schemes, for example, in microfluidic and/or millifluidic devices. In many of these processes, it is often helpful to maintain controlled separation between two liquid phases and/or between a liquid phase and a gas phase. For example, in many processes, liquid-liquid and/or a gas-liquid separations are performed (e.g.
