This study uses high-speed 3D tracking to show SARS-CoV-2 uses actin for membrane trafficking, preceding viral entry, and correlates with ACE2 expression.

This study uses 3D-SMART microscopy to analyze nanoparticle diffusion in agarose gels, revealing hopping diffusion and structural insights with super-resolution.

This paper develops a method to measure single-nanoparticle electrophoretic mobility and trap them using 3D tracking with active feedback, showing improved precision over ensemble methods.

This paper introduces StayGold fluorescent protein fusions to enable long-duration, high-speed 3D single-virus tracking in live cells.
