Topography and recognition imaging of protein-patterned surfaces generated by AFM nanolithography.
Native-protein nanolithography is combined with topography and recognition imaging to synergistically use AFM tips to write and image nanoscale protein patterns on a surface (see picture). The approach is validated with different feedback modes, using surface-bound biotinylated bovine serum albumin (BSA) protein and AFM tips carrying streptavidin.
