for the reason that implementation of impermeable pigments in color sensors is not simple, some host materials ought to be used for making the nanoporous pigments through the sol−gel approach. Nanoporous pigments can be created to enhance the sensitivity, durability, stability, and hydrophobicity of colorimetric sensors. Ormosil sol-gel matrix with high stability, large surface area, and proper hydrophobicity is an outstanding porous matrix that is not suffering from changes in relative humidity from 10 to 90%. adding a plasticizer to polymer-based colorimetric films will increase the hydrophobicity of the polymer matrix in addition to protecting towards moisture. Inorganic films with nanoporous structures such as TiO₂-based nanoporous film as a substrate can be another opportunity to reduce moisture interference in colorimetric sensing structures. Hydrogels are a group of promising soft materials with highly water-swellable three-dimensional hydrophilic polymer networks, which can be extensively utilized in sensing. Hydrogels can act as a host matrix to immobilize sensing probes and adjust the diffusion of analytes into the sensor network.
