Movie Gallery Welcome to the Molecular Expressions website featuring our acclaimed photo galleries that explore the fascinating world of optical microscopy. We are going where no microscope has gone before by offering one of the Web's largest collections of color photographs taken through an optical microscope commonly referred to as "photo-micro-graphs".

Visit our Photo Gallery for an introductory selection of images covering just about everything from beer and ice cream to integrated circuits and ceramic superconductors.

These photographs are available for licensing to commercial, private, and non-profit institutions. The Universe Within - Soar through space starting at 10 million light years away from the Milky Way down through to a single proton in Florida in decreasing orders of magnitude powers of ten.

This tutorial explores the use of exponential notation to understand and compare the size of things in our world and the universe, and provides a glimpse of the duality between the macroworld around us and the hidden microworld within.

Electromagnetic Radiation - Visible light is a complex phenomenon that is classically explained with a simple model based on propagating rays and wavefronts, a concept first proposed in the late s by Dutch physicist Christiaan Huygens.

Electromagnetic radiation, the larger family of wave-like phenomena to which visible light belongs also known as radiant energyis the primary vehicle transporting energy through the vast reaches of the universe.

The mechanisms by which visible Discussion on simple staining is emitted or absorbed by substances, and how it predictably reacts under varying conditions as it travels through space and the atmosphere, form the basis of the existence of color in our universe Spinning Disk Confocal Microscopy - Spinning disk microscopy has advanced significantly in the past decade and now represents one of the optimum solutions for both routine and high-performance live-cell imaging applications.

The rapid expansion in biomedical research using live-cell imaging techniques over the past several years has been fueled by a combination of events that include dramatic advances in spinning disk confocal microscopy instrumentation coupled with the introduction of novel ultra-sensitive detectors and continued improvements in the performance of genetically-encoded fluorescent proteins.

Spectral Imaging and Linear Unmixing - Spectral imaging and linear unmixing is becoming an important staple in the microscopist's toolbox, particularly when applied to the elimination of autofluorescence and for FRET investigations.

Instruments equipped for spectral imaging are becoming increasingly popular and many confocal microscopes now offer this capability. Widefield fluorescence and brightfield microscopy are also being used more frequently for resolving complex fluorophore and absorbing dye mixtures, a trend that should continue into the future.

Fluorescent Protein Technology - It took over thirty years, and the advent of recombinant DNA as well as vastly improved molecular biological approaches to see the pioneering work of Osamu Shimomura developed into a useful tool for live-cell imaging by Doug Prasher and Martin Chalfie.

Just in the past decade, however, we have witnessed a truly remarkable expansion in the fluorescent protein palette, largely driven by the innovative studies from Roger Tsien's laboratory.

Most of the fluorescent proteins that are commonly used today have been modified through mutagenesis to optimize their expression in biological systems.

Continued efforts using directed evolution approaches will no doubt improve the spectral characteristics, photostability, maturation time, brightness, acid resistance, and utility of the fluorescent protein tags for cellular imaging.

Carl Zeiss MicroImaging Online Campus - Visit the new ZEISS website that explores the fascinating world of optical microscopy and provides the necessary background to understand both the basic concepts and advanced principles.

Included are review articles, interactive Flash tutorials, reference materials, and image galleries. Light Sources for Optical Microscopy - The performance of the various illumination sources available for optical microscopy depends on the emission characteristics and geometry of the source, as well as the focal length, magnification and numerical aperture of the collector lens system.

In gauging the suitability of a particular light source, the important parameters are structure the spatial distribution of light, source geometry, coherence, and alignmentthe wavelength distribution, spatial and temporal stability, brightness, and to what degree these various parameters can be controlled.

Live-Cell Imaging - An increasing number of investigations are using live-cell imaging techniques to provide critical insight into the fundamental nature of cellular and tissue function, especially due to the rapid advances that are currently being witnessed in fluorescent protein and synthetic fluorophore technology.the material attributes of paints.

Paint can be used more effectively once you understand the material attributes of paint and how these attributes affect its behavior. Simple Staining: Colouration of microorganisms by applying single dye to a fixed smear is termed simple staining. One covers the fixed smear with stain for specific period, after which this solution is washed off with water and slide blotted dry.
