Nanotechnology 'pencil sharpeners' add to researchers' nanofabrication toolbox

Abstract:
Proponents of 'atomically precise manufacturing' and 'molecular manufacturing' love to talk about the mind-boggling possibilities that these technologies would offer. These visions range from the modest, such as improved materials and more efficient production methods for chemicals (already on the horizon), to the outrageous, such as molecular desktop fabs (far, far out). Articles about revolutionary nanotechnology almost always skip the hard part, i.e. the tremendous amount of research breakthroughs that are required to get from where we are today to the promised land. It's as if some flight enthusiasts in 1903, when Orville Wright took off on the first powered flight, would have debated first class cabin design of 600-seat jet airliners flying New York - Tokyo non-stop. Nanotechnology researchers today are still struggling with very basic problems such as being able to control the synthesis of nanoparticles. It might come as a bit of a shock to the nanotechnology enthusiasts among you, but even something utterly fundamental as synthesizing metal nanoparticles today is more of an empirical trial and error approach than a predictable, fully controlled process. Let's take a look at new research coming out of a Spanish university that exemplifies the tiny, yet elementary, steps researchers need to take to master the nanoscale.
