Although this article does emphasize the very cool things that can be done with CNTs and nanoparticles, it does say that "Nanoparticles could potentially give an insulator like silicon the ability to conduct electricity". Unless the author is talking about doping silicon (technically particles at the nano-scale, but no one considers them freestanding nanoparticles since they are integrated into the Si lattice) to make it more conductive, he/she is simply wrong. Silicon does conduct electricity, albeit poorly (eg, non-enhancement mode transistor). That line alone makes the whole article suspect.
