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: 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: A microfluidic system for causing perturbations in a cell membrane, the system including a microfluidic channel defining a lumen and being configured such that a cell suspended in a buffer can pass therethrough, wherein the microfluidic channel includes a cell-deforming constriction, wherein a diameter of the constriction is a function of the diameter of the cell.

Abstract: A method and device for preferentially delivering a compound such as an antigen to the cytosol of an immune cell. The method comprises passing a cell suspension comprising the target immune cell through a microfluidic device and contacting the suspension with the compound(s) or payload to be delivered.
