The increasing interest in halides and halogen oxyanions monitoring has led to a strong demand of sensitive and selective analytical methodologies for their determination. In this sense, the implementation of nanostructures in analytical systems has been profusely explored in recent years for optical sensing of halides and halogen oxyanions in samples of varying complexity. The present work provides a critical overview of contributions devoted to colorimetric and luminescent determination of relevant halogen-containing species by taking advantage of the unique properties of NPs. Particular attention has been paid to the different strategies followed for optical sensing of target analytes. In addition, analytical validation of reported methods is critically evaluated and guidance for compliance with validation requirements is provided.
