Fluorometry of absorbant and turbid samples and the lateral mobility in membranes of intact erythrocytes.

Intrinsic and extrinsic fluorophores attached to large biological assemblies (e.g. cells) find many useful applications in biophysics and medical science. Since such samples frequently absorb and/or scatter light strongly, special techniques have been developed for dealing with the artifacts which result. The use of excimerization probes as indicators of the local lateral mobility in the membranes of intact red and blood cell provides an illustration.
