Abstract

This specification generally relates to a biphasic injectable electrode which comprises a plurality of solid particles and a transporter phase, wherein both the solid particles and the transporter phase comprise poly(3,4-ethylenedioxythiophene)polystyrene sulfonate. The biphasic injectable electrode, in use in a surgical resection cavity in the brain includes inserting the biphasic injectable electrode into a surgical resection cavity in the brain with a tumor resection margin. A probe is inserted into the electrode and four counter electrodes are implanted in the surrounding brain tissue. A charge delivery device delivers charge to the probe via a wire both of which have also been implanted.
