Correlative Multi-Modal Microscopy: A Novel Pipeline for Optimizing Fluorescence Microscopy Resolutions in Biological...

Area of Science:

• Optical microscopy
• Cell biology
• Biophysics

Background:

• Modern fluorescence microscopy faces limitations in balancing statistical sampling, signal analysis, and spatial resolution.
• Maximizing one parameter often compromises others, hindering comprehensive cell biology studies.
• Super-resolution microscopy offers high spatial resolution but is limited in region size and cell count.

Purpose of the Study:

• To present a correlative microscopy pipeline integrating diverse optical techniques.
• To overcome the trade-offs inherent in individual microscopy methods.
• To achieve high statistical sampling, high content, and maximal spatial resolution simultaneously.

Main Methods:

• Integration of widefield, confocal, and molecular localization microscopy techniques.
• Development of a correlative acquisition and analysis pipeline.
• Application of the pipeline to cell biology samples.

Main Results:

• Demonstration of a correlative approach that merges data from different spatial scales.
• Achievement of high statistical sampling, high content, and maximum spatial resolution.
• Overcoming the limitations of single-modality microscopy for in situ macromolecular complex exploration.

Conclusions:

• Correlative microscopy, by fusing different optical technologies, surpasses the limitations of individual methods.
• The developed pipeline enables comprehensive analysis of cellular structures at multiple scales.
• This integrated approach facilitates broader adoption of advanced optical microscopy tools in research laboratories.
