Chemically Sensitive Resistors Based on Monolayer-Capped Cubic Nanoparticles: Towards Configurable Nanoporous Sensors

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 spher...

Description
Summary:	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).
