Abstract: Isolating or identifying a cell based on a physical property of said cell can include providing a cell suspension; passing said suspension through a microfluidic channel that includes a constriction; passing the cell suspension through the constriction; and, contacting said cell suspension solution with a compound. The constriction can be sized to preferentially deform a relatively larger cell compared to a relatively smaller cell.

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: The current subject matter includes methods, systems, articles, and techniques to deliver material to anucleate cells, such as red blood cells. Using a rapid deformation based microfluidic system, loading of red blood cells with macromolecules of different sizes has been shown. Although delivery to some mammalian cells, such as cancer cell lines and fibroblasts had been previously demonstrated using this technique, those designs were incompatible with RBCs that have dramatically different physical properties. Through the use of smaller constriction sizes, high speeds and different buffers successful delivery to red blood cells can be achieved. By enabling robust delivery to red blood cells in a simple, scalable manner, the current subject matter can be implemented in a diversity of applications that deliver material to study red blood cell diseases and/or use red blood cells as a therapeutic platform. Related apparatus, systems, techniques, and articles are also described.

Abstract: Method of separation of a radiometal ion from a target metal ion, comprising a first liquid-liquid extraction step in which an organic phase comprising an extractant and an interfacial tension modifier is mixed with an aqueous phase comprising the radiometal ion and the target metal ion in order that the radiometal ion is at least partially transferred to the organic phase, followed by a first phase separation step, wherein the phase separation is carried out in flow comprising the use of a microfiltration membrane to separate the phases based on the interfacial tension between the phases such that a permeate phase passes through the membrane and a retentate phase does not.

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.
