Mastering
single-molecule FRET:
A practical handbook for researchers
Understand the fundamentals of smFRET and explore its potential in your own research
Discover everything you need to understand single-molecule FRET and use it to advance your research
This practical smFRET handbook brings together the core principles, experimental workflows, and analytical strategies that underpin modern single-molecule Förster Resonance Energy Transfer (smFRET). Designed for researchers at every stage – from newcomers to seasoned practitioners – it distils the essential knowledge required to generate high-quality smFRET data and interpret it with confidence.
Inside, you’ll find:
Clear, accessible explanations of key concepts such as FRET efficiency, stoichiometry, ALEX, burst analysis, and accurate FRET correction
Step-by-step descriptions of how a confocal smFRET instrument works, how single molecules are detected, and how to ensure true single-molecule sensitivity in practice
Illustrative examples and case studies showing how smFRET resolves structural heterogeneity, conformational dynamics, and nanoscale distance changes in biomolecules
Comparisons to complementary single-molecule and structural biology techniques, helping you understand when – and why – smFRET is the method of choice
Insights into powerful analytical approaches, including E–S plotting, burst search strategies, and correction-factor estimation for high-precision distance measurements
Download this guide if you want to:
✓ introduce a simple, solution-based method into your existing workflows that rapidly resolves conformational changes at the single molecule level
✓ complement existing static workflows with dynamic data
✓ unlock deeper functional insights and novel biological questions
