Answer
Fluorescent dyes are biological molecules that are made up of at least one fluorophore, which is a molecule that emits light on excitation by light energy. 
  • Offer higher specificity and sensitivity
  • Can be used to label live as well as fixed cells
  • Can be used to localize and track specific cellular components
  • Photostable and long-lasting
  • Can be multiplexed for labeling multiple targets simultaneously 
  • Can be used for quantitative analysis
  • Compatible with multiple imaging techniques
