    摘要: The invention relates to a probe arrangement (10g) for exchanging in a controllable way liquids with micro-sized samples of material like biological cells, especially in connection with an scanning probe microscope, said probe arrangement (10g) comprising a probe holder (11) with at least one embedded first channel (18) and a cantilever (12) with at least one embedded second channel (15) and being provided to be attached to said probe holder (11) in a way that at least one aperture (19) of the first channel (18) is connected to at least one aperture (17) of the second channel (15) in a way that permits the liquid-tight transfer of a liquid between said first and second channels (15, 18). A safe and easy use of the probe arrangement is achieved by having the cantilever (12) permanently attached to said probe holder (11) to form a prefabricated probe unit (10g).

    摘要: A probe arrangement with a probe for local electrophysiological analysis of cells (4) such as patch-clamp techniques for use with atomic force microscopy, has a probe with a cantilever arm (2) connected to a probe holder (3). The probe has a probe tip (4) at a probing end (5) of the cantilever arm (2) and a fluid channel (6) in the cantilever arm (2) connecting a probe tip aperture (7) with a fluid reservoir (8) via a duct (9). The fluid channel (6), the duct (9) and the fluid reservoir (8) are adapted to be filled with a fluid solution (10) enabling ion transport for electrophysiological analysis. A first electrode (15) for electrophysiological analysis is placed in the fluid reservoir (8) and/or in the duct (9) and/or in the fluid channel (6).
