Paper Abstract

A recent technique optimizing the detection of small birefringences typical of biological liquid crystals has been described elsewhere. Here, we derive a liner relationship between color intensity, molecular birefringence and degree of phase alignment, based on which, a quantitative image analysis is developed. The image analysis is used to define the dynamics of the phase transition-like increase in color intensity accompanying the condensation of the body-wall musculature in the maturing Drosophila larva, to map the orientation of the collagen fibers in the intervertebral disc, and to investigate mesophases of pork skin collagen assembled in vitro.
