Extractions: En 1953, le physicien néerlandais Frits Zernike (1888-1966) reçut le prix Nobel de la physique pour avoir développé la méthode du contraste de phase qui a révolutionné la microscopie des objets vivants. De concert avec la firme Carl Zeiss (Kurt Michel, Walter Loos, August Köhler), il avait conçu en effet, en 1936, le prototype d'un microscope permettant de mettre en pratique le nouveau procédé de contraste de phase. Plusieurs procédés de contraste et types d'observations sont utilisés de nos jours pour rendre visibles les structures d'une préparation microscopique. Jusqu'au début des années 30, il était pratiquement impossible de visualiser au microscope des objets vivants ou non colorés avec une qualité suffisante. Frits Zernike résolut ce problème, en mettant au point la méthode du contraste de phase qui met à profit l'effet exercé par les objets non colorés sur la phase des rayons lumineux qui les traversent. Les différences de phase invisibles causées par les détails de l'objet sont transformées en variations d'intensité lumineuse visibles. Cette méthode a permis de restituer des échantillons biologiques pour la première fois avec un bon contraste, sans les colorer artificiellement. Peu après la mise au point du microscope à contraste de phase, les chercheurs de Carl Zeiss à Iéna se mirent à tester les premières applications, en commençant par la visualisation de chromosomes dans des cellules vivantes. Le premier film en accéléré réalisé au laboratoire de microscopie de Carl Zeiss fit sensation en 1943, en visualisant la division cellulaire, phénomène qui est à l'origine de la vie. Des avances décisives réalisées par la suite dans le domaine de la recherche biologique et médicale auraient été inconcevables sans l'apport du microscope à contraste de phase. La méthode qui en est à la base a été ainsi récompensé à juste titre par le prix Nobel. Elle est aujourd'hui appliquée quotidiennement en microscopie de routine.

Extractions: Nederlandse winnaars van de Nobelprijs voor de natuurkunde Het jaartal verwijst naar het jaar waarin de prijs werd toegekend. Bij de Nobelprijzen gaat het vaak om bekroning van al veel eerder uitgevoerd onderzoek. 1902: Hendrik Antoon Lorentz en Pieter Zeeman De drie kort opeenvolgende Nobelprijzen van Lorentz en Zeeman, Van der Waals en Kamerlingh Onnes tonen aan dat Nederland honderdvijftig jaar geleden een kennisland werd. Grote trendzetters waren Nederlands belangrijkste politicus Thorbecke en de Nobelprijswinnaar Hendrik Antoon Lorentz (1853-1928, foto links). Thorbecke ontnam de koning van Oranje via de grondwet zijn macht, en legde in een andere wet vast dat de regering veel belastinggeld moest besteden aan onderwijs met veel wis- en natuurkunde en talen. Die hogere burgerschool werd opgericht in 1863, waardoor er goed opgeleide mensen kwamen. De eerste gediplomeerden zoals Lorentz ontwikkelden een wetenschappelijke programma: begrijpen hoe verschijnselen voortkomen uit het gedrag van atomen en moleculen. Later overtuigde Lorentz de politici ervan instituten op te richten voor het toepassen van die kennis (TNO). Daarnaast kon Nederland met wetenschappelijke berekeningen van Lorentz de Afsluitdijk bouwen die mensen rond het IJsselmeer voortaan voor waterrampen behoedde.

Extractions: Edited by the QA-talk Editorial Team on 19 November 2003 The achievements of Frits Zernike, his pioneering work with Carl Zeiss, and his early recognition by the Royal Microscopical Society commemorated at joint RMS/Carl Zeiss Meeting Scientists from around the world gathered in London recently to celebrate a half-century of achievement in cell biology and look at future techniques for live cell research. The occasion was the 50th Anniversary of the Award of the Nobel Prize to Dutch scientist, Frits Zernike, for his discovery of the phase contrast method and the invention of the Phase Contrast Microscope. The meeting was jointly sponsored by Carl Zeiss, which built the first Phase Contrast microscope in 1936 and pioneered live cell applications throughout the period until 1945, and The Royal Microscopical Society, the first learned body to recognise the significance of Zernike's work.

Movie Gallery A large spectrum of living biological specimens are virtually transparent when observed in the optical microscope under brightfield illumination. To improve visibility and contrast in such specimens, microscopists often reduce the opening size of the substage condenser iris diaphragm, but this maneuver is accompanied by a serious loss of resolution and the introduction of diffraction artifacts. Phase contrast was introduced in the 1930's for testing of telescope mirrors, and was adapted by Zeiss laboratories into a commercial microscope several years later. This technique provides an excellent method of improving contrast in unstained biological specimens without significant loss in resolution, and is widely utilized to examine dynamic events in living cells. Brief Overview of Phase Contrast - The search was still on in the early part of the twentieth century to find a way of using both direct and diffracted light from all azimuths to yield good contrast images of unstained objects that do not absorb light. Research by Frits Zernike during this period uncovered phase and amplitude differences between zeroth order and deviated light that can be altered to produce favorable conditions for interference and contrast enhancement. Phase Contrast Microscopy - Phase contrast microscopy, first described in 1934 by Dutch physicist Frits Zernike, is a contrast-enhancing optical technique that can be utilized to produce high-contrast images of transparent specimens such as living cells, microorganisms, thin tissue slices, lithographic patterns, and sub-cellular particles (such as nuclei and other organelles). In effect, the phase contrast technique employs an optical mechanism to translate minute variations in phase into corresponding changes in amplitude, which can be visualized as differences in image contrast. One of the major advantages of phase contrast microscopy is that living cells can be examined in their natural state without being killed, fixed, and stained. As a result, the dynamics of ongoing biological processes in live cells can be observed and recorded in high contrast with sharp clarity of minute specimen detail.

In effect, the phase contrast technique employs an optical mechanism to translate minute variations in phase into corresponding changes in amplitude, which can be visualized as differences in image contrast. One of the major advantages of phase contrast microscopy is that living cells can be examined in their natural state without previously being killed, fixed, and stained. As a result, the dynamics of ongoing biological processes can be observed and recorded in high contrast with sharp clarity of minute specimen detail.
