Progress in the Correlative Atomic Force Microscopy and Optical Microscopy.

Area of Science:

• Biophysics
• Nanotechnology
• Microscopy

Background:

• Atomic force microscopy (AFM) excels at morphological imaging and molecular interaction detection at the nanoscale.
• Limitations of AFM include non-specificity, low imaging speed, and inability to precisely capture synchronized molecular groups, hindering mechanism and structure elucidation.
• Combining complementary techniques is crucial for detailed molecular interaction and dynamics studies.

Purpose of the Study:

• To review the principles of Atomic Force Microscopy (AFM) and various optical microscopy techniques.
• To highlight the development and application of correlative AFM and optical microscopy.
• To address the technical limitations of AFM by integrating it with optical methods.

Main Methods:

• Review of Atomic Force Microscopy (AFM) principles.
• Discussion of optical microscopy techniques including confocal microscopy and single-molecule localization microscopy (SMLM).
• Exploration of correlative approaches combining AFM with optical microscopy.

Main Results:

• AFM provides high-resolution topographical and interaction data at the molecular level.
• Optical microscopy techniques offer complementary information on molecular identity, dynamics, and synchronized group behavior.
• Correlative AFM and optical microscopy enable a more comprehensive understanding of molecular interactions and dynamics.

Conclusions:

• The integration of AFM with optical microscopy overcomes individual technique limitations.
• Correlative microscopy is a vital approach for detailed investigation of molecular interactions and dynamics.
• This combined approach significantly advances nanoscale research in biophysics and nanotechnology.
