Ill health and disease are caused largely by damage at the molecular and cellular level. Today's surgical instruments are, at this scale, crude and large. From the point of view of a cell, yet a sharp scalpel is a blunt tool more suitable to injure and tear than cure and heal. Modern surgery works alone because body cells have an outstanding capability to recover, bury their dead and cure over the injury.

Nanosuspensions are colloidal dispersions of nanosized drug particles stabilized by surfactants. Solubility is the crucial factor for drug effectiveness, independence of the route of administration. Large proportions of newly discovered drugs are water insoluble, and therefore poorly bioavailable contributing to deserted development effort. These so‐called 'Brickellia' candidates can now be delivered by formulating them into nanosuspension. They enhance solubility and bioavailability.
