Inhibition of retinal angiogenesis by gold nanoparticles inducing autophagy.

Aim: To investigate the effect of gold nanoparticles on retinal angiogenesis and , and to reveal the possible mechanism.

Methods: Seed growth method was used to synthesize gold nanoparticles (GNPs). The size, zeta potential, absorption spectrum and morphology of GNPs were identified using Malvern Nano-ZS, multimode reader (BioTek synergy2) and transmission electron microscope.
