Abstract (EN): Despite the ancient visual detection origins, established at the end of the XIX century and raised through the early XX century, in recent years it has acquired a renovated relevance as research has been focused on the development of fast, expeditious, cost-effective and easy to handle analytical methodologies, for on-site monitoring of distinct analytes, from pollutants, to food contaminants, pharmaceuticals, biomarkers, pathogens, etc. This work examines fluorescence-based visual detection methods resorting to quantum dots, either alone or in combination with other molecules and nanoparticles, discussing the formats employed to implement sensing platforms, including strategies for enhanced sensitivity and selectivity, multianalyte determinations, detection modes, sensors assembly, readout acquisition and processing, etc. The different types of quantum dots used, from binary to ternary nanocrystals, the tailoring of their surface chemistry with appropriate molecules for target recognition, the implementation of multi-detection schemes and the panoply of analytes determined, are also comprehensively examined.
