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.

The invention relates to a device designed for the cultivation and radiation-induced killing of living biological cells. The device comprises a flat substrate and a functional layer for creating a wound in biological cells, said functional layer being applied to the flat substrate. The functional layer contains at least one photosensitizer which is designed to convert triplet oxygen into singlet oxygen by the application of electromagnetic radiation. As a result, biological cells on the functional layer can be killed by irradiation of low-intensity electromagnetic radiation. A wound can be introduced into a cell layer at a locally defined point easily, quickly, carefully, and in a flexible and cost-effective manner and thus the healing of the wound can be studied. The invention further relates to uses of the devices and a method for analyzing a migration and/or wound healing behavior of biological cells.

A substance introduction device introduces a substance into a cell by electroporation, and includes at least one substance introduction unit including an accommodation container that accommodates a cell suspension containing the cell and the substance and a pair of electrodes that applies a voltage to the cell suspension accommodated in the accommodation container; and a liquid delivery unit that delivers a liquid to the accommodation container. The accommodation container has a first and a second openings, and the liquid delivery unit fills the accommodation container with the cell suspension before voltage application through the first opening and to discharge the cell suspension after the voltage application from the accommodation container through the second opening, and to fill the accommodation container with a cleaning solution through the second opening and to discharge the cleaning solution from the accommodation container through the first opening.

An electroporation system may include a well plate, a dispenser and a dispenser-well positioning system. The well plate may include wells, each of the wells including an interior, a first electrode adjacent the interior and a second electrode adjacent the interior and spaced from the first electrode. The first electrode and the second electrode are to apply an electrostatic field across the well. The dispenser is to dispense a cell having a diameter into each of the wells. The dispenser-well positioning system is to align each well and the dispenser such that the dispenser dispenses the cell into each well at a location spaced from the first electrode and the second electrode by a distance of at least 5 times the diameter of the cell.

The producing method according to the disclosed technology is a producing method for an organism-derived material into which a bioactive substance has been introduced, the producing method comprising a step of causing a suspension containing the organism-derived material before the introduction of the bioactive substance and containing the bioactive substance to pass through a first electric field region having a first electric field intensity; and a step of causing the suspension to pass through a second electric field region having a second electric field intensity lower than the first electric field intensity after the suspension has passed through the first electric field region. The organism-derived material is a human-derived cell.
