Fig. 4From: Surface force analysis of glycine adsorption on different crystal surfaces of titanium dioxide (TiO2) a Specific adhesion curve obtained on TiO2 (001) surface. b Unbinding force histogram. MPF for glycine on TiO2 (001) surface at a loading rate of 6 nN/s (pH 7.4). Fitting was performed using a Gaussian fit and showed a mean force of 92.85 ± 33.72 pNBack to article page
