Abstract:
1. A probe arrangement with a probe for analysis of material for use with atomic force microscopy (AFM), wherein said probe arrangement comprises: a cantilever arm connected to a probe holder, wherein said cantilever arm has a thickness in the Y-direction which is greater than the thickness in the Z-direction; a sharp, microfabricated probe tip at a probing end of said cantilever arm; a fluid channel in said cantilever arm connecting a probe tip aperture with a fluid reservoir via a duct running through said probe holder, wherein said fluid channel, said duct and said fluid reservoir are adapted to be filled with a fluid solution enabling ion transport for electrophysiological analysis, wherein said fluid reservoir is equipped with a pressure controller and a flow controller in order to enable controlled delivery or suction via said probe tip aperture; and wherein a first electrode is suspended in at least one of the following locations: said fluid reservoir; in the duct; and in said fluid channel.
