Image analysis of dark field images obtained at low magnification can be combined with analyzes of images obtained in respect of the same section of a sample and same magnification but with other techniques such as fluorescent microscopy. The system and method can be used e.g. for particle counting, particle size measurement, particle size distribution, morphology measurement, where the particles can be cells and/or cell parts. The invention also relates to a compact dark field light source unit, a system or apparatus including a microscope which by itself is compact and comprises the mentioned dark field light source unit.

Abstract: Disclosed is a fast and simple method for quantification of nucleic acid of biological cells as 2-step protocol. In the first step cells are treated with an acidic solution containing a non-ionic detergent and a fluorescent DNA specific label. In the second step the sample may be neutralized. Determining of the content of nucleic can be performed by fluorescence microscopy. The method may also be used for obtaining information of cell cycle analysis, ploidy determination, measurements of nucleotide incorporation and assays for proliferation, health, stress level, apoptosis, necrosis, or other state of conditions of cells. The invention also relates to a kit of parts comprising an acidic agent, a detergent, a labelling agent and optionally a neutralization agent.

Abstract: A method and a device for the assessment of at least one parameter of particles in a liquid analyte material are disclosed. The method comprises providing a device having a sample compartment with an exposing domain, an inlet through which a volume of a liquid sample representing the analyte material can been introduced, and a flow system comprising at least a channel allowing at least a portion of the volume of the liquid sample to flow within the device. The volume of the liquid sample passes into the exposing domain of the sample compartment, which can quantitatively detect spatial image data and process the detected image electromagnetic signals from the sample in the exposing domain of the device. A spatial image representation of the exposing domain, and processing the detected image presentation obtaining the assessment of the at least one parameter is generated in the device.
