Two grafting architectures were examined: hydrophilic-hydrophobic (AB-type) diblock PGNPs and reverse BA-type diblock PGNPs. Our findings reveal that AB-type diblock PGNPs tend to aggregate, leading to droplet-droplet coalescence. In contrast, BA-type diblock PGNPs disperse effectively in the water phase, stabilizing robust emulsion through a space-filling mechanism. The study further demonstrates that the stability and morphology of the emulsions can be tuned by varying the number of PGNPs.

The ongoing efforts to reduce these side effects are hampered by the generally poor understanding of its mode of action and behavior in solution. A key question that has been debated is whether colistin self-assembles into micelles or remains as unimers in solution. Herein, we used synchrotron small-angle X-ray scattering (SAXS), small-angle neutron scattering (SANS), and molecular dynamics (MD) to show that colistin <em>does not</em> self-assemble in a wide range of physiologically relevant conditions.

The interplay of capillary and Marangoni flow influences assembly at both macro and nanoscales, with the deposition process and nanoparticle ordering being highly sensitive to interparticle and nanoparticle-substrate interactions.
