3D Nano Molecular Structures Can Be Built On A Surface

3-D molecular structures can be built on a surface by introducing a ‘guest’ molecule; molecules are built upwards from a surface rather than just 2-D formations as previously achieved. This breakthrough was achieved by scientists at The University of Nottingham.

A natural biological process known as ‘self-assembly’ meant that once the scientists introduced other molecules on to a surface their host then spontaneously arranged them into a rational 3-D structure.

Professor Neil Champness said: “It is the molecular equivalent of throwing a pile of bricks up into the air and then as they come down again they spontaneously build a house.

“Until now this has only been achievable in 2-D, so to continue the analogy the molecular ‘bricks’ would only form a path or a patio but our breakthrough now means that we can start to build in the third dimension. It’s a significant step forward to nanotechnology.”

The new process involved introducing a guest molecule — in this case a ‘buckyball’ or C60 — on to a surface patterned by an array of tetracarboxylic acid molecules. The spherical shape of the buckyballs means they sit above the surface of the molecule and encourage other molecules to form around them. It offers scientists a completely new and controlled way of building up additional layers on the surface of the molecule.

Science fiction fans recall the autofac from the 1955 Philip K. Dick short story of the same name:

The cylinder had split. At first he couldn't tell if it had been the impact or deliberate internal mechanisms at work. From the rent, an ooze of metal bits was sliding. Squatting down, O'Neill examined them.

The bits were in motion. Microscopic machinery, smaller than ants, smaller than pins, working energetically, purposefully - constructing something that looked like a tiny rectangle of steel.

"They're building," O'Neill said, awed.
