Abstract

A so-called discotic phase of liquids of certain organic molecules was established experimentally some three decades ago. Following quite recent work in which a single red blood cell (RBC) has been isolated in a microdroplet, the question has been raised in this Journal as to whether an assembly of such cells, each having the shape of a di-concave disc, can form an amorphous aggregate. Here, we propose that a disordered discotic phase can exist, in which a RBC is in interaction with its neighbouring cells. We also note that if, as has been proposed earlier, the shape of a di-concave disc is mathematically simplified to that of a finite length cylinder, then it turns out that Onsager, six decades ago, had anticipated such a disordered nematic phase of rods.
