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.
Claims21
A colorimetric 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 is different from the second nanoporous pigment.
A method of making a colorimetric array, comprising:
- depositing a first liquid at a first point on a substrate,
- depositing a second liquid at a second point on a substrate,
- converting the first liquid into a first spot on the substrate, and
- converting the second liquid into a second spot on the substrate;
- where the first spot comprises a first nanoporous pigment comprising a first nanoporous material and a first immobilized, chemoresponsive colorant, and
- the second spot comprises a second nanoporous pigment comprising a second nanoporous material and a second immobilized, chemoresponsive colorant, and
- the first nanoporous pigment is different from the second nanoporous pigment.
