Nanocrystal links could lead to better electronics, scientists say

Chemists and engineers today are very interested in a kind of nanotechnology enabled by tiny islands of nanoparticles called `colloidal nanocrystals.` They can be made out of abundant and non-toxic materials, and they can be easily tweaked to have a number of different properties as a function of their size. Depending on how they`re built, colloidal nanocrystals could be made into solar panels, electronics or optical devices. But all of these applications require making nanocrystals friendly places for electrons to travel along.
