WebOptical profilometry (OP), also known as White Light Interferometry (WLI), is a non-contact interferometric-based method for characterizing surface topography. A typical optical profilometer analysis provides 2D and 3D images for surface analysis, numerous roughness statistics and feature dimensions. WebApr 7, 2024 · Researches show that the topography of biomaterials plays an important role in regulating cell proliferation, adhesion, and differentiation. It is of great significance to understand how cell aggregates respond to surface topography. Herein, microdisk array structures with the optimized size are used to investigate the wetting of cell aggregates.
