Nanoscale fluid flows used to probe thin films...
Two teams of researchers in France have measured the rigidity of a material without touching it. The method involves a tiny amount of fluid flowing over the surface of the material and is non-invasive and non-destructive.
As such, the technique could be used to achieve nanometre-scale analysis of the elastic properties of thin films or fragile objects such as bubbles or living cells...
