Abstract
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).
