This review details recent advances in digital imaging (DI) methods for the development of analytical methodologies combining quantum dots (QDs). The art-of-art, treatment of data, apparatus, software, chemical sensors, and optimization of such methods are reported. Due to their versatility, portability, low-cost, fast analysis, and high throughput, DI presents itself as a powerful methodology to detect the optical changes in quantum dots. Applications of the technology for the analysis of food and beverages, biomedically relevant analytes, drugs, environmental samples and forensic samples are discussed. Overall, these examples show that the combination of DI-QDs represents a powerful option to measure different analytes with good accuracy and precision. It was also observed that the versatility and greenness of the methods are being increasingly reported in the literature, providing a way to compare the environmental impact of the methods reported.
