Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods rely on adhesive or mechanical forces to hold and scan cells, which limit their applicability to suspended cells and may induce stress responses. Developing a non-contact, all-optical 3D imaging technique for live suspended cells remains a major challenge in advancing in situ biological research.
