From: Selection of peptides binding to metallic borides by screening M13 phage display libraries
Analysis of the phage binding by fluorescence microscopy. Confocal fluorescence (A, C) and transmission optical microscopy (B, D) of LGFREKE phage bound to amorphous (A, B) and crystalline (C, D) Ni3B nanoparticles. The samples were dyed using a fluorescently tagged anti-M13 monoclonal antibody. Confocal fluorescence (E, G) and transmission optical microscopy (F, H) of the control experiments of amorphous and crystalline Ni3B nanoparticles, respectively, which were preincubated with M13KE wild-type (M13wt) phage before incubation with the fluorescently tagged antibody.
