Forisomes - ATP-independent mechanoproteins - as potential nanomotors

In vitro, forisomes exhibit anisotropic contractility energized by changes in free Ca2+

concentration of the bathing solution. Changes of calcium concentrations in the nanomolar range as well as pH changes trigger alterations in the forisome architecture. Mechanical forces of appreciable magnitude - not far from the forces produced by muscle cell contractions - are exerted in condensation and expansion. Their range of fascinating properties (rapid, reversible, anisotropic, ATP-independent, capacity to pull and to push) make them excellent candidates for use in micro- and nanotechnological devices.
