Development of rapid, sensitive, safe, enconomical methods for food analysis and detection has become a hot
topic of common concern worldwide. As newly emerging fluorescence nano probes, quantum dots have been used in an
expanded range from material sciences, biolology and medicine to food field, stimulating the development of food analysis
and detection techniques. This review focuses on optical properties of quantum dots and recent applications in food analysis
and detection. Quantum dots with special properties and some suggestions for improved applications are outlined. Moreover,
recent applications of newly emerging quantum dot probes in food safety detection and nutrient analysis are summerized
aiming to provide some guidelines for the development of food detection and analysis.

Key words: quantum dots, optical properties, food, application
