Dynamic light scattering (DLS) was applied for size determination. Malvern Zetasizer Nano ZS (Model S, Ver. 2.15, Malvern Panalytical, Malvern, UK) was used to measure the mean diameter, polydispersity index (PDI), and zeta potential (ZP) of LTZ-GA-AuNPs. The hydrodynamic diameter was evaluated after suspending the prepared colloidal nanoparticles in deionized water. The extent of DLS was prepared through a laser wavelength of 633.0 nm at 25 °C by a revealing angle of 90°. All samples were analyzed in triplicate and the three cycles were averaged.
