Colorimetric assays

Colorimetric assays are laboratory techniques used to measure the concentration of a substance by assessing the color change in a solution. When a chemical reacts with a specific analyte, it produces a color that can vary in intensity. By comparing this color to a standard reference, scientists can determine the amount of the substance present. These assays are commonly used in various fields, such as healthcare, environmental monitoring, and food safety, as they offer a straightforward and cost-effective way to analyze samples and obtain quantitative results.
