Cube roots: Chemiresistors based on cubic monolayer-capped nanoparticles (MCNPs) produce a higher electrical response upon exposure to volatile organic compounds than those based on spherical MCNPs. These observations are explained in terms of the higher swellability of cubic MCNPs compared to spherical MCNPs (see picture).
