Many natural microscopic objects—red blood cells and pollen grains, for example—take the form of distorted spheres. The distortions can be compared to those observed when a sphere is ‘deflated’ so that it steadily loses internal volume. Until now, most of the work done to understand the physics involved has been theoretical. Now, however, Gwennou Coupier and his colleagues at Grenoble Alps University, France have shown that macroscopic-level models of the properties of these tiny spheres agree very well with this theory. The new study, which has implications for targeted drug delivery, was recently published in The European Physical Journal E.
