DLS measurements were performed at an incident wavelength of 633 nm at a fixed angle of 173° by averaging 3 runs of 30 seconds long using Zetasizer Nano (Malvern Panalytical). The time correlation function of scattered intensity was analyzed by CUMULANT and CONTIN methods. The VLP concentration was adjusted to 0.1 mg/mL in filtered PBS and VDB before measurements.
