(A) The DLS assay for GQD-HA-Qu shows a Z-average particle size of 224.96 nm, a PDI of 0.3, and a mean number diameter of 76.89 nm, with a zeta potential of −43.38 mV. (B) The field emission scanning electron microscopy (FESEM) micrograph displays a dispersed population of spherical GQD-HA-Qu NCs with a narrow distribution, indicating successful conjugation and a stable colloidal system. (C) The transmission electron microscopy (TEM) micrograph of GQD reveals particles with spherical to irregular shapes, measuring under 10 nm in size, typical of a heterogeneous distribution of quantum dots.
