FIG. 3.

Approach curves for C. parapsilosis-modified cantilever approaching a bare silicone rubber surface. The inset figures show curves for a bare cantilever (squares) and an HDT-coated cantilever (circles) on the same material. Attractive events exist for each system. Panel A shows the data analyzed according to the Ducker and Senden method (16), while panel B was analyzed by contact mechanics (9). The modified probe has the strongest interactions with the cell-modified probes and the weakest interactions with the HDT-modified probes. Note that the different data analysis techniques do not change the interaction for a bare probe on silicone rubber.
