Selective Plane Illumination Microscopy SPIM

Selective Plane Illumination Microscopy (SPIM) is a powerful imaging technique used in biological research. It offers 3D imaging with high resolution and contrast, making it a valuable tool for studying dynamic processes within living organisms.

Advantages of SPIM

  • Wide field of view: Allows for imaging of large sample volumes.
  • High resolution: Provides detailed images with submicron resolution.
  • Minimal photobleaching: Preserves sample integrity during imaging.
  • Low phototoxicity: Suitable for live cell imaging.

Applications of SPIM

  • Embryonic development: Studying organ and tissue formation in early stages.
  • Neuroscience: Visualizing neural circuits and synaptic activity.
  • Cancer research: Imaging tumor growth and metastasis dynamics.
  • Developmental biology: Monitoring morphogenesis and tissue remodeling.

Technical Principle

SPIM operates by selectively illuminating a single plane of the sample at a time. Light is focused onto the sample through an objective lens located perpendicular to the imaging axis. Fluorescence emitted from the illuminated plane is collected by a detection system, resulting in a cross-sectional image. By scanning the illumination plane through the sample volume, a 3D reconstruction of the specimen can be obtained.
