Nanotomography of Cell Surfaces with Evanescent Fields
Figure 6
TIRF image of YFP-FAK (, ) as well as (b) topology of focal adhesions prior and (c)
after PDT with ALA-induced PP IX (633 nm; 4 J/cm2). Fluorescence excited at 514 nm and
detected at 520−550 nm; image size: 140 m 140 m; cell-substrate distances
(colour scale) given in nanometres.
