Peptidesomes are nanoparticles that are built by a two-step self-assembly of globular peptide dendrimers with lysine endgroups (red spheres in picture) and poly(L-leucine) carrying one glutamic acid residue (blue lines with red dot). These viral-capsid-mimicking nanoarchitectures exhibit high gene transfection efficacy and thus are promising nonviral vectors for biomedical applications.
