Fig. 3From: Surface force analysis of glycine adsorption on different crystal surfaces of titanium dioxide (TiO2) a Specific adhesion curve obtained on TiO2 (100) surface. b Unbinding force histogram. MPF for glycine on TiO2 (100) surface at a loading rate of 6 nN/s (pH 7.4). Fitting was performed with a Gaussian fit and showed a mean force of 96.24 ± 34.22 pNBack to article page
