Abstract: Abstract: Single molecule fluorescence detection has been more and more broadly applied in life sciences. Complementary to traditional ensemble experiments, this technique can quantitatively and carefully explore the chemical mechanism behind a biological process. We present some typical systems studied by single molecule fluorescence detection to demonstrate its feature, advantage, and application. These examples involve important biological processes, from simple to complex reactions.
Key words: single molecule detection; fluorescence; biological process; chemical mechanism
