摘要:
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.

An object of the invention is to provide an electroporation method for treating vesicles with exogenous material for insertion of the exogenous material into the vesicles which includes the steps of: a. retaining a suspension of the vesicles and the exogenous material in a treatment volume in a chamber which includes electrodes, wherein the chamber has a geometric factor (cm−1) defined by the quotient of the electrode gap squared (cm2) divided by the chamber volume (cm3), wherein the geometric factor is less than or equal to 0.1 cm−1, wherein the suspension of the vesicles and the exogenous material is in a medium which is adjusted such that the medium has conductivity in a range spanning 0.01 to 1.0 milliSiemens, wherein the suspension is enclosed in the chamber during treatment, and h. treating the suspension enclosed in the chamber with one or more pulsed electric fields. With the method, the treatment volume of the suspension is scalable, and the time of treatment of the vesicles in the chamber is substantially uniform.

摘要:
A TPSRM may include a stator, having a plurality of poles and a ferromagnetic or iron back material, and a rotor having a plurality of poles and a ferromagnetic or iron back material. A current flowing through coils wound around a first set of the plurality of stator poles induces a flux flow through the first set of stator poles and portions of the stator back material during a first excitation phase. A current flowing through coils wound around a second set of the plurality of stator poles induces a flux flow through the second set of stator poles and portions of the stator back material during a second excitation phase. The numbers of stator and rotor poles for this TPSRM are selected such that substantially no flux reversal occurs in any part of the stator back material as a result of transitioning between the first and second excitation phases.
