Abstract

A method to provide a microfluidic flow comprising a central flow and at least one outer flow, such that the central flow includes a first material and the at least one outer flow comprises a second material. One of the first material and the second material has cells and the other of the first material and the second material has solid particles. The method involves injection of a first suspension including the first material through a central inlet with a flow rate Q2 and injection of a second suspension comprising the second material through a pair of side inlets with a flow rate Q2, whereby the ratio of the flow rate Q2 over the flow rate Q1 is at least 4. A device provides such microfluidic flow and a method is provided to alter biological cells.
