STED uses a differential method of two different diffraction patterns, where one pattern excites and the second pattern de-excites fluorochromes. The residual excited area is controllable by intensity down to (theoretically) zero – unlimited resolution.
Hoffman modulation contrast has established itself as a standard for the observation of unstained, low-contrast biological specimens. The integration of the modulator in the beam path of themodern inverted microscopes allows a wide range of brightfield or phase objectives to be used, rather than a small selection of special objectives.
“Confocal Microscopy” refers to a particular optical microscope that allows recording optical sections. Optical sectioning is achieved in a confocal system by illuminating and observing a single diffraction limited spot.
An insight into the unknown world of the deep sea was given in an exhibition staged by the Senckenberg Society together with the Natural History Museum in Basel, Switzerland. Shown in Frankfurt am Main and Berlin, Germany, the "Deep Sea" exhibition was a huge public success in 2009. From May to September 2010, the exhibition has been shown in the Natural History Museum in London. Scientists of the Senckenberg Society work with stereomicroscopes and digital cameras both in the laboratory and on the research ships.
Laser dissection is used in a large number of research fields, e.g. neurology, cancer research, plant analysis. Here, user report on the research results they have attained by using laser microdissection.
