Abstract :
We demonstrate a nanofluidic-based carbon dioxide sensor through corroboration with our nanochannel hydronium-dominated ion transport model. We verify the predictive power of our model by comparing calculated and measured conductances of solutions with added HCl in both bulk and in nanochannel geometries. From thus model, we use our experimental system to determine the carbon-dioxide content in the ambient atmosphere.
