Based on the well-known spatial extension of the observation volume, the diffusion coefficient, D, and, by using the Stokes–Einstein equation (see Experimental), the hydrodynamic radius of the fluorescent particle, RH, can be calculated. Consequently, a NP size increase due to

Three independent series of measurements were taken and averaged. Data analysis In conventional FCS
