    • The rate of precipitation was observed to be higher for the assembly process at 50 °C as compared to that at the lower temperature.

    • note
    • In a separate experiment, the protein-nanoparticle assemblies obtained at 23 °C were annealed to a temperature of ∼80 °C, over a 18 h period. Thereafter, SAXS performed on the annealed samples did not show any change in the interparticle spacings, displaying the robust nature of assembly and the resistance of cross-linked protein against denaturation by heat.

    • note
    • Due to the nature of the assembly obtained, it is difficult to determine the exact thickness of bound protein and correlate it quantitatively to the surface plasmon peaks.

    • MMPC 1, alone, was kept in solution at 50 °C for overnight. No change in the absorbance maxima or aggregation in solution was observed, displaying that the nanoparticles were stable under the assembly conditions at the higher temperature.

    • note
    • For the samples assembled at higher temperatures, additional absorbance peaks at ∼460 nm are observed. The origin of these peaks is unknown at present and could be due to either local dielectric effects or short-range anisotropy in the assembly process.
