Abstract:

The colorimetric method is a common detection method in biosensing, which has received much attention because of its high sensitivity and specificity. Among them, multicolor colorimetric method based on multicolor probes has become a hot research topic in recent years. Its sensitivity is significantly higher than that of monochromatic colorimetric method, and it has higher resolution which can be visualized for semi-quantitative detection by naked eye recognition, quickly quantified by calculating color ratios or based on smartphone image processing software. Based on three different color development mechanisms: organic small molecule fluorescence, nanomaterial color development and enzymatic reaction color development, the detection mechanisms of multicolor fluorescent small molecule probes, multicolor nanomaterial colorimetric probes and multicolor enzymatic reaction colorimetric probes are reviewed and their applications in practical sample detection are discussed. The challenges and future development opportunities are also discussed.
