a Schematic illustration of magneto-responsive deformation and electrochemical detection. b Fluorescence image of MC3T3-E1 cells stained with Calcein-AM (green) and PI (red) after being cultured on MRnM@FeP/s-P sensor for 36 h. c Side view of the confocal microscope images of MRnM@FeP/s-P (fuchsia) and MC3T3-E1 cells (green) under magneto-responsive deformation. d, e Amperometric responses and (f) the corresponding quantitative analysis of NO molecules detected from MC3T3-E1 cells under different deformation amplitudes. The vertical gray dashed lines indicate the beginning of deformation. Applied potential: +0.80 V (vs. Ag/AgCl). Data are presented as mean ± s.e.m.; two-tailed Student’s t-test (n = 3, for each group).
