Wave Retardation

We developed an anisotropic nano-imprinting technique, which combines the exposure of ultraviolet light, to fabricate a patterned optical film of a liquid crystalline polymer (LCP). The nano-imprinted LCP film has two-fold functionality of an in-cell retarder and an alignment layer of liquid crystal (LC) molecules. In addition to the geometrically generated microgrooves, the anisotropic surface interactions of the LCP acquired at a nano-scale level during the imprinting process results in the LC alignment on the patterned LCP film without any surface treatment. The nano-imprinted, quarter wave LCP was implemented into a LC cell which produces half-wave retardation under crossed polarizers.

Multi Mode

We have developed a multi-mode digital imaging system which acquires images with a cooled CCD camera (Figure 1). A multiple band pass dichromatic mirror and robotically controlled filter wheels provide wavelength selection for epi-fluorescence. Shutters select illumination either by epi-fluorescence or by transmitted light for phase contrast or DIC. Many of our experiments involve investigations of spindle assembly dynamics and chromosome movements in live cells or unfixed reconstituted preparations in vitro in which photodamage and phototoxicity are major concerns. As a consequence, a major factor in the design was optical efficiency: achieving the highest image quality with the least number of illumination photons. This principle applies to both epi-fluorescence and transmitted light imaging modes. In living cells and extracts, microtubules are visualized using X-rhodamine labeled tubulin. Photoactivation of C2CF-fluorescein labeled tubulin is used to locally mark microtubules in studies of microtubule dynamics and translocation. Chromosomes are labeled with DAPI or Hoechst DNA intercalating dyes.
