Quantum Dots in Milk Adulteration

Adulteration of milk and milk products is a serious concern for the dairy industry.Adulteration not only cheats the consumer, but also results in various health implications.Various methodologies have been devised over decades for detecting adulterants in milk.However, some of these methods have limitations in sensitivity, while others; although very sophisticated and sensitive, involve complicated sample preparation.Quantum dots with versatile applications have shown competency in overcoming the above said limitations.Quantum dots exhibit excellent fluorescent characteristics, which form the basic foundation for their usage in this field.In this paper, we discuss the different types of quantum dots which have been used over the recent years to detect various adulterants which are commonly found in milk.
