Control experiments using polydopamine and silica probes. (a–f) Adhesion force (a, c, e) and rupture length (b, d, f) histograms, together with representative force curves, obtained by recording force curves between polydopamine-coated probes and C. albicans germinating yeasts (a, b) or germ tubes (c, d), and between silica probes and C. albicans germ tubes (e, f). For each probe, similar data were obtained in 3 independent experiments.
