Abstract:
We compare the spatial resolution and image contrast of an erythrocyte surface obtained by means of scanning force microscopy (SFM) with conventional hydrophobic Si probes and probes modified by hydrophilic Pt/C whisker probes. It is shown that probes with Pt/C nanowhiskers provide a higher spatial resolution and contrast when imaging relief on the surface of erythrocytes. The contrast inversion is revealed in some areas of the SFM images when replacing Si probes by probes with Pt/C nanowhiskers. The origin of this inversion in the tapping and contact modes is discussed.
