How the tiniest sieve in the world could improve dialysis

Abstract:
Don't you just love serendipity? Christopher Striemer does. As a research associate at the University of Rochester in the US, Striemer recently discovered a new ultrathin silicon membrane that could revolutionise the way that doctors or scientists manipulate molecules. Only 50 atoms thick, it might even improve treatment regimes for haemodialysis patients with kidney failure.

A self-driven and inquisitive scientist who likes doing things well, Striemer was trying to understand how silicon - as used in computer chips - crystallises. As part of his research into semiconductors under Philippe Fauchet, professor of electrical and computer engineering, he made a thin silicon membrane and placed it in an electron microscope. At first glance, it appeared full of holes. But instead of trying again, he stopped in amazement.
