Kim et al. created a sensitive, inexpensive

Kim et al. created a sensitive, inexpensive gq0r7
Kim et al. created a sensitive, inexpensive, selective colorimeter sensor array by printing 10 indicators on PET film to detect toxic industrial gases (ammonia, methylamine, trimethylamine, and hydrazine). The colorimetric ink becomes stabilized on the substrate via solvent evaporation and a sol-gel mechanism. here they used the printing approach because the drop-casting method has numerous drawbacks: it is impossible to control the thickness, width, and form of each spot. in addition, depending on the chemical composition of the solution, the substrate, and the index, the coffee ring effect may be created all through drying to create a non-uniform spot. The effect of the coffee ring is because of the thickness of the colorimetric spot implemented to the substrate, and thickness is a critical element related to the initial color value and the gas sensitivity. here, a colorimetric spot can be controlled on a substrate within the preferred shape and thickness and can offer the basis for mass production. similarly, the manufacturing of sensors using the printing approach can produce massive quantities of chips at a low cost and in a short time. external light sources make it hard for the CMOS image sensor to detect great color changes that lead to designing the structure of the detector to minimize them. this structure permits sensitive detection of small color changes of the colorimetric array, and the gas detection results additionally can be monitored in real-time using a smartphone and central control machine through wireless transmission.
