Colorimetric sensors are widely used for various sensing applications due to their specificity, sensitivity, cost-effectiveness, and ease of use. They have been developed to detect a range of substances including metal and non-metal ions, proteins, small molecules, gases, viruses and bacteria, DNA/RNA, acidity/base, and biomarkers in clinical diagnostics. Recent advancements in nanomaterials have played a significant role in the development of colorimetric sensors. This article provides an overview of the field, discussing the design and fabrication of sensors for various applications such as alkaline vapors, dopamine detection, uric acid detection, organic thiol analysis, H2O2 and glucose detection, HPV detection, metal ion detection, protein identification, synthetic food dye detection, and phenolic compound detection. These sensors offer promising applications in different fields, providing rapid, low-cost, and portable solutions for detection. The article also highlights the development of multifunctional sensors and the integration of colorimetric sensors with smartphones, color-recording devices, and optical sensing arrays, which have improved the portability, sensitivity, and specificity of detection. The article concludes that with further advancements in materials and analytical chemistry, colorimetric sensors will continue to contribute to the fields of chemical and biological sensing.
