  1. Zav values obtained via dynamic light scattering (nanoparticles in deionized water) and TEM are presented. τ values were measured on fluorescence spectrometer (‘Fluo’), τϕ and intensity-weighed τm values were obtained on FLIM microscope (‘FLIM’) via phasor (80 MHz) or decay fitting approaches (see Methods for more details)
