A colorimetric sensor (20) has a first material (22) deposited on a surface, and sensing particles (24) on a surface of the first material (22), wherein the sensing particles (24) comprise sensing species (26) dispersed into porous host structures, such that at least a portion of the sensing particles (24) is exposed to an ambient environment, wherein the first material (22) attaches the sensing particles to (24) a surface. A method of forming a colorimetric sensor (20) including depositing (30) a first material (22) onto a substrate, providing (32) porous sensing particles (24), wherein the sensing particles (24) comprise sensing species (26) dispersed into a porous host structure, and embedding the porous sensing particles (24) onto a surface of the deposited first material (22), wherein the first material (22) attaches the sensing particles (24) to the substrate such that at least a portion of the sensing particles (24) is exposed to an ambient environment. |
