In this video, I explain FRET (Fluorescence Resonance Energy Transfer) in a clear and easy way so you can actually understand the concept instead of just memorizing it.

We’ll start from the basics—what FRET really is—and then move step by step into how energy transfers from a donor fluorophore to an acceptor molecule without emission of light. I’ve also explained why distance is so important (1–10 nm range!) and how even a small change can completely affect the efficiency.

You’ll also learn:

Donor and acceptor concept
Mechanism of FRET (step-by-step)
Förster radius and why it matters
Spectral overlap and crosstalk
Common donor–acceptor pairs (like CFP–YFP, Cy3–Cy5)
Real applications like protein–protein interaction and DNA/RNA studies

I’ve also included a simple explanation of Green Fluorescent Protein (GFP) and its variants, which are widely used in FRET experiments.

This topic is very important for:

BSc / MSc Biology students
CSIR NET, GATE, NEET PG exams
Anyone studying molecular biology or biophysics
