Understanding the Colorimetric Principle

At its core, a colorimetric assay relies on a chemical reaction that produces a colored product作者：L Wei·2015·被引用次数：58—We report apeptide-basedcolorimetricstrategy for the detection of disease biomarker by using vascular endothelial growth factor receptor 1 (Flt-1) as an .... The intensity of this color is directly proportional to the concentration of the analyte being measured – in this case, peptides. This principle allows for quantitative analysis by measuring the absorbance of light at a specific wavelength using a spectrophotometer. The Pierce Quantitative Colorimetric Peptide Assay, for instance, is a well-established example of this technology. These assays typically involve mixing a sample containing peptides with specific reagentsDetection of Cardiac Troponin I | ACS Sensors. The reaction then leads to the formation of a colored complex, which can be easily detected and quantified. The detection method is fundamentally colorimetric, making it accessible even in laboratories without highly specialized equipment.
