Nano-scratch test of the time-lateral displacement data for a, g TiO2@LDGC, c, i Al2O3@LDGC, e, k TiO2/Al2O3@LDGC; Nano-scratch test of the time-normal force for b, h TiO2@LDGC, d, j Al2O3@LDGC, f, l TiO2/Al2O3@LDGC; The insets in (a–l) are schematic diagrams of LDGC coated with different thin films. The reduced elastic modulus (m, o) and hardness (n, p) of LDGC, TiO2@LDGC, Al2O3@LDGC, TiO2/Al2O3@LDGC. Statistical significance was analyzed using one-way ANOVA with Tukey’s multiple comparisons test. For the reduced elastic modulus, NS is not significant. For the hardness of UP.CAD, P(LDGC-Al2O3@LDGC) < 0.01, P(LDGC-TiO2@LDGC) < 0.01, P(LDGC-TiO2/Al2O3@LDGC) < 0.01. For the hardness of IPS e.max CAD, P(LDGC-Al2O3@LDGC) < 0.05, P(LDGC-TiO2@LDGC) < 0.05, P(LDGC-TiO2/Al2O3@LDGC) < 0.01. Data are presented as mean ± s.d. of n = 5 biological replicates. Error bars represent s.d. Source data are provided as a Source Data file.
