The invention relates to a method for spatially manipulating a microscopic object including providing a cantilever () having a tip with an opening () and a microchannel () extending through the cantilever () in its longitudinal direction. A suspension means is provided for holding the cantilever () and spatially moving the cantilever along a predetermined spatial path. A pressurizing means is provided for applying a predetermined pressure to the microchannel () and the cantilever () is moved with its tip to the microscopic object to be spatially manipulated. At least a part of the microscopic object is picked up with said cantilever () by reducing the pressure within the microchannel () relative to the pressure outside the tip of the cantilever (). The microscopic object is then moved along a predetermined spatial path by means of the cantilever ().

The invention relates to a probe arrangement () 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 () comprising a probe holder () with at least one embedded first channel () and a cantilever () with at least one embedded second channel () and being provided to be attached to said probe holder () in a way that at least one aperture () of the first channel () is connected to at least one aperture () of the second channel () in a way that permits the liquid-tight transfer of a liquid between said first and second channels (). A safe and easy use of the probe arrangement is achieved by having the cantilever () permanently attached to said probe holder () to form a prefabricated probe unit ().
