Figure 2.

Figure 2

a) AFM image of scFv antibodies covalently bound to carbon nanotubes, with a typical density of 4–5 attachment sites per micrometer of nanotube length. Scale bar is 1 μm. Height scale is 7 nm. b) Histogram of the heights of the white features bound to the nanotube in Fig 2a shows a maximum at ~ 2.5 nm, consistent with the expected height of scFv antibodies. Secondary maxima at 5 nm and 7.5 nm are attributed to small aggregates of scFv antibodies. The total number of features analyzed is 180.
