1. A sensor system comprising:
a sensing element comprising plural individual pillars of layer assemblies deposited onto a substrate, the plural individual pillars of layer assemblies each comprising a plurality of nanoparticle layers and open regions for interaction between nanoparticles and a fluid, wherein a first nanoparticle layer of the plurality of nanoparticle layers comprises nanoparticles of a first material configured to sense a first analyte fluid component of the fluid and a second nanoparticle layer of the plurality of nanoparticle layers comprises nanoparticles of a second material different from the first material and configured to sense a second analyte fluid component of the fluid different from the first analyte fluid component, wherein the sensing element is configured to generate two or more sensor signals responsive to one or both of the nanoparticles of the first material being in the presence of the first analyte fluid component or the nanoparticles of the second material being in the presence of the second analyte fluid component when in contact with the fluid; and
one or more processors configured to receive the two or more sensor signals from the sensing element, the one or more processors configured to identify the first analyte fluid component, the second analyte fluid component, or both within the fluid, an amount of the first analyte fluid component or the second analyte fluid component within the fluid based on the two or more sensor signals, or a combination thereof.
