摘要： The invention relates to a scanning force microscope, which can be used for different examinations of the surfaces of samples. The aim of the invention is to provide a scanning force microscope, by which surface regions of samples can be detected, which are oriented at a steeply inclined angle with respect to the central longitudinal axis of a cantilever of the scanning force microscope. In the scanning force microscope according to the invention, at least one sensor tip is disposed on the cantilever, the sensitive region of which is disposed at a distance from the cantilever. To this end, the cantilever which is held on a face and can be prompted to oscillate using at least one actuator can be moved with the sensor tip and sample relative to each other along at least one axis. The sensitive region of a sensor tip and/or the base of a sensor tip are disposed on the cantilever with a distance and next to the center longitudinal axis of the cantilever. Either alone or additionally, the sensor tip can be angled or curved at an angle of

摘要： The invention relates to a method and a device for detecting tumorous living cell tissue. It also relates to a method and a device for detecting tumorous cell tissue in collected samples of living cell tissue. In the method, a radiation source is used to emit electromagnetic radiation in a locally defined manner onto cell tissue and, after the radiation source has been switched off, the decay behaviour of the inherent fluorescence intensity excited in the cell tissue by the electromagnetic radiation is detected on the cell tissue by a detector, with temporal and spectral resolution and with a known scanning rate or known scanning rates for at least one wavelength. With the measured intensity values that are obtained, the difference autocorrelation function C(t) of the intensity decay behaviour is determined, from which the fractal dimension D
F for the respective irradiated cell tissue is calculated, and the value of the fractal dimension D
F is used for a classification in respect of a tumorous invasion of the respective irradiated cell tissue.
