- The Nobel Prize in chemistry goes to three men who revolutionized microscopy (Rachel Feltman, The Washington Post) This is another example of the overlap between sciences. The techniques developed could just as well be classified as physics while the applications could be classified as biology and medicine. The scientists awarded were trained as chemists so perhaps that is the rationale for recognizing this work as chemistry. The three chemists developed techniques of using pulsed light and processes that might be thought of as similar to time-lapse photography to resolve images of molecular structures far smaller than the theoretical limits imposed by the wavelength of light. Animal cells have dimensions of the order or 1 micron up to tens of microns for the largest cells (micron = micrometer = 10-6 meters = 4 x 10-5 inches – 0.00004 inches). See Wikipedia for a list of things with dimensions larger than 10 microns and also smaller than 10 microns.
The major substructure elements of cells are called “organelles” and many have dimensions less than 0.1 micron. At the theoretical limit of visible light resolution (0.2 to 0.4 micron, depending on wavelength with blue resolving better than red) cell images are resolvable, although often with fuzzy resolution imparted by the practical limitations of the optics elements degrading resolution to less than the theoretical limit. Very few very large organelles are detectable with visible light and only with extremely poor resolution.
The new technology can resolve individual molecules and by superposition of molecular images produce very high resolution images of even the smallest organelles. It has been used to study the operational steps in nerve cells, protein behavior in cells associated with Huntington’s disease and cell division in embryos. All these studies are conducted in vivo with no interference with the natural processes taking place.
