Abstract
The device of the invention comprises a support having a surface comprising an attachment zone (Z) capable of being functionalized with a probe (A) capable of binding, according to the pH and reversibly, to a target (B) so as to attach it; a working electrode (WE) and a counterelectrode (CE) for this working electrode, arranged on the support in the vicinity of the attachment zone; and means for applying a given electric current or a given potential to said working electrode so as to cause, when said attachment zone and said electrodes are immersed in an aqueous solution, a local variation in pH in the region of said attachment zone. The method for attaching and/or detaching a target or an object according to the invention uses this device, the attachment and/or the detachment being electrochemically controlled with the working electrode.
