Abstract
A method of forming a colorimetric sensor includes depositing a first material onto a substrate, providing porous sensing particles, wherein the sensing particles comprise sensing species dispersed into a porous host structure, and embedding the porous sensing particles onto a surface of the deposited first material, the first material attaching the sensing particles to the substrate with at least a portion of the sensing particles is exposed to an ambient environment.
