Synthesis and characterisation of uniform CoPt nanoparticles using red blood cell ghosts conjugated with peptides on their inner surface.

We have demonstrated the potential of red blood cell ghosts (RBCGs) conjugated with a cobalt platinum (CoPt)-binding peptide as a scaffold for synthesising CoPt nanoparticles (NPs). The results of characterisation experiments showed that the NPs prepared using peptide-conjugated RBCGs were larger, more uniform, and had a higher Co content and improved magnetic properties.
