Abstract: In order to check a material for transplantation, at least one Raman spectrum (41, 42) of the material is detected. An electronic evaluation device determines an information, from which depends a suitability of the material for use during the transplantation, by evaluating the at least one Raman spectrum (41, 42).

Abstract: A method and device for quality controlling a blood-based product. In order to control the quality of a blood-based product which comprises an erythrocyte concentrate, a thrombocyte concentrate, a granulocyte concentrate, a leukocyte concentrate, whole blood and/or blood plasma, a Raman spectrum is recorded. By means of evaluating the Raman spectrum, it is determined whether the blood-based product can be used for a transfusion.

Abstract: The invention relates to a device (1) for detecting and/or evaluating a pathological condition comprising a Raman spectroscopy system (10) and an electronic evaluation device (20), which is configured to perform a detection and/or evaluation of the pathological condition in accordance with an evaluation of at least one Raman spectrum detected in stroma.

Abstract: The invention relates to a device for analyzing biological objects comprising a Raman spectroscopy system for capturing at least one Raman spectrum. The device comprises an arresting apparatus, which is designed to at least temporarily arrest the biological objects. An electronic computing apparatus is designed to determine a reaction of a biological object arrested by the arresting apparatus to at least one substance in accordance with an evaluation of the at least one Raman spectrum.

Abstract: In order to identify a prostate tumor with a Raman spectroscopy system, at least one Raman spectrum (40) of a sample is detected. The at least one Raman spectrum (40) is evaluated in order to identify a prostate tumor and/or distinguish an aggressive from a non-aggressive prostate tumor based on a characteristic pattern in the at least one Raman spectrum (40).

Abstract: In order to quantitatively characterize biological objects, for example individual cells, a stimulus is applied to a biological object in a contactless fashion. A measurement and a further measurement are performed on the biological object in order to ascertain a response of the biological object to the stimulus, wherein the measurement and the further measurement comprise detecting Raman scattering on and/or in the biological object and/or capturing data using digital holographic microinterferometry (DHMI). The biological object is characterized according to a result of the measurement and is sorted if needed. The stimulus can be applied by means of a laser beam that creates optical tweezers or an optical trap, by means of ultrasonic waves or an electric or magnetic radio frequency field.
