Since several years, time-resolved fluorescence measurements can be performed with commercially available confocal laser scanning microscopes (LSM) that have been upgraded with a suited upgrade kit. The polarization extension for PicoQuant's upgrade kit for LSM can now also perform polarization measurements.

Diplozoid monogenean Eudiplozoon nipponicum, with complex life cycle comprising oncomiracidium, diporpa, juvenile and adult stage, represents an ideal model for studies on morphological adaptations of metazoan parasites to the ectoparasitic life style. Combined morphological approach offers the advantage of more complex characterization and visualization of structures noticeable only when using specific microscopic method.

Olympus has introduced UPLSAPO30xS and UPLSAPO60xS, two new silicon immersion objectives for life science imaging.
The lenses are ideal for live cell experiments, particularly those investigating thick samples or requiring long-term imaging.

A laser scanning microscope collects information from a thin focal plane, disregarding out-of-focus information. It has become the standard imaging method to characterise cellular morphology and structures, both in static and living samples. Laser scanning microscopy at high resolution combined with digital image restoration is also a powerful tool to analyse intracellular localisation of fluorescently labelled nanoparticles (NPs), such as their colocalisation within membrane-bound compartments (e.g.

By removing out-of-focus light from above and below the focal plane, particularly in specimens >20 µm thick, the Olympus Disk Scanning Unit (DSU) uniquely delivers confocal-like images with excellent contrast and resolution compared to conventional wide-field microscopy. To reject the out-of-focus light, the DSU places a spinning disk, with an alternating pattern of vertical and horizontal slits, in the confocal plane of the microscope.

Fluorescence Recovery after Photobleaching (FRAP) is a versatile technique to study dynamic phenomena. Performing FRAP on a confocal laser scanning microscope documents the recovery process with high spatial resolution. This enables a consistent determination of the diffusion coefficient and the dimensionality of diffusion in calibration-free manner. Moreover, experiments representing multi-component diffusion can be analyzed as well, thus yielding the distribution of diffusion coefficients
