In vitro, multiple electrode pair array and multiple treatment cell apparatus for use in electroporation

A multiple electrode pair array apparatus for use with a multiple well plate having multiple wells distributed in a two-dimensional matrix array having R rows and C columns, comprising:

• a non-conductive base member,
• an array of pairs of electrodes attached to said base member and projecting therefrom, wherein said pairs of electodes are distributed on said base member in a two-dimensional matrix array having R rows and C columns to enable registration with the two-dimensional matrix array of wells, wherein each pair of electrodes includes a respective first electrode and a respective second electrode,
• an array of R row conductors attached to said non-conductive base member, wherein each row conductor is electrically connected to corresponding first electrodes in a corresponding row of first electrodes, and
• an array of C column conductors attached to said non-conductive base member, wherein said C column conductors are perpendicular to said R row conductors, wherein each column conductor is electrically insulated from said row conductors, wherein each column conductor is electrically connected to corresponding second electrodes in a corresponding column of second electrodes.
