Ordered High Density Phase Growth in Magnetic Fields

Ordered High Density Phase Growth in Magnetic Fields

High density liquid crystalline DNA phase development occurs in a very orderly fashion when influenced by a combination of an established concentration gradient and high magnetic fields. The image presented above demonstrates the long-range periodicity seen in these phases when conditions are ideal. The magnification is approximately 75x, and the image was recorded on Fujichrome 64T transparency film using a Nikon Optiphot-Pol microscope with crossed polarized illumination. Exposures were recorded about 3 f-steps under the recommended value given by an in-camera photomultiplier and were push-processed approximately 1.5 f-steps in the first E-6 developer.
