1. A colorimetric sensor array comprising:
- a substrate;
a first spot on the substrate, comprising a first nanoporous pigment, the first nanoporous pigment comprising a first nanoporous material and a first immobilized, chemoresponsive colorant; and
a second spot on the substrate, comprising a second nanoporous pigment, the second nanoporous pigment comprising a second nanoporous material and a second immobilized, chemoresponsive colorant;
where the first nanoporous pigment differs from the second nanoporous pigment, andwhere the first and second nanoporous pigments are cross-reactive with one another with respect to at least one analyte,where the first immobilized, chemoresponsive colorant comprises a chemoresponsive pigment,where the chemoresponsive pigment is a porous pigment.

Abstract
A colorimetric array includes a substrate, a first spot on the substrate, and a second spot on the substrate. The first spot includes a first nanoporous pigment that includes a first nanoporous material and a first immobilized, chemoresponsive colorant. The second spot includes a second nanoporous pigment that includes a second nanoporous material and a second immobilized, chemoresponsive colorant. The first nanoporous pigment is different from the second nanoporous pigment.
