Histidine-Functionalized Diblock Copolymer Nanoparticles Exhibit Enhanced Adsorption onto Planar Stainless Steel
Summary
Sterically stabilised diblock copolymer nanoparticles of tunable size (about 70 to 190 nm) were converted to carry histidine groups, which gives them an isoelectric point near pH 7 while keeping them dispersed. QCM measurements at pH 6 show that the histidine particles adsorb onto stainless steel far more than the unmodified ones, up to 70.5 mg per square metre, with about 23% surface coverage seen by SEM.
