From: Atomic force microscopy characterization of kinase-mediated phosphorylation of a peptide monolayer
AFM topographic scan of peptide layer on ultra-flat gold after each step of the process.
After peptide deposition; (b) After phosphorylation; (c) After dephosphorylation; Inset in (a) is the same area with a square scratch at the center. The profile on top demonstrates layer width (2.5 nm) and uniformity.
