Relationship between lateral deflection distance and CTFs and cross-sectional CTF distribution of CD4 T cells. (a) The relationship between the lateral deflection distance (y displacement) and CTFs of the CD4 T cell acting on the QNPA substrates using nonlinear model in COMSOL Multiphysics® software. (b) Cross-sectional CTF distribution of the CD4 T cell on STR-QNPA substrates, exhibiting that the CTFs at the edge of the cells are much stronger than those at the center part of the cells.
