Abstract
A colorimetric sensor has a first material deposited on a surface, and sensing particles on a surface of the first material, wherein the sensing particles comprise sensing species dispersed into porous host structures, such that at least a portion of the sensing particles is exposed to an ambient environment, wherein the first material attaches the sensing particles to surface. A method of forming a colorimetric sensor including 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, wherein the first material attaches the sensing particles to the substrate such that at least a portion of the sensing particles is exposed to an ambient environment.
