Condition :   Excellent  
Principle :   Fluorescence    
Area of Study :  Modern Physics  
Equipment :   Quantum Dots, UV lights.

  
Procedure :   Quantum Dots are structures with the same composition but different sizes.  The size determines the color with which it fluoresces.   These are generally used as markers to monitor  chemical, genetic, and protein reactions.
