Area of Science:

• Virology
• Microscopy
• Biophysics

Background:

• Viral infections pose significant societal threats, as highlighted by the COVID-19 pandemic.
• Studying viral structures and infection mechanisms is key to developing effective treatments.
• Conventional microscopy limits the visualization of nanoscale viral components and protein organization.

Purpose of the Study:

• To review the application of super-resolution microscopy (SRM) in studying viral infection.
• To highlight SRM's role in characterizing viral structures and protein clusters.
• To discuss SRM's potential in antiviral design and understanding emerging viruses.

Main Methods:

• Super-resolution microscopy (SRM) techniques are employed to overcome the diffraction limit.
• SRM achieves resolutions up to 10 nm using fluorescent probes.
• Various SRM methods are available for detailed viral studies.

Main Results:

• SRM enables high-resolution characterization of viruses like HIV-1, Influenza, and SARS-CoV-1.
• It facilitates the study of protein cluster organization within viral particles.
• SRM aids in quantifying and modeling viral infection steps at the nanoscale.

Conclusions:

• SRM is a powerful tool for understanding viral infection mechanisms.
• Its application is vital for the development of novel antiviral strategies.
• SRM can guide future research on emerging viruses and antiviral design.
