What is the major advantage of structured illumination microscopy (SIM)?

#Unit 13. Methods in Biology
  1. SIM is particularly suited for live cell imaging as it is not very phototoxic and allows for a high temporal resolution
  2. The resolution in lateral dimension is below 5 nm
  3. It combines fluorescence microscopy and electron microscopy allowing to study small structures in great details
  4. Sample in SIM are coated with metal ions
