where 𝑘 B is the Boltzmann constant, 𝑇 the absolute temperature, 𝜂 𝑠 the viscosity of the solvent, and D the diffusion coefficient. The measurements were performed on a light scattering setup equipped with an ALV-SP125 goniometer, an ALV/LSE5004 multi tau correlator, a fiber optical ALV/High QE APD avalanche photodiode with pseudo-cross correlation and a uniphase He/Ne laser (632.8 nm, Thorlabs Inc.). Details of the DLS analysis are described in the SI Chapter 7.
