摘要: Abstract Ranibizumab is a first-line therapy against age-related macular degeneration. For further improvement of ranibizumab-based treatment, we developed ranibizumab biosimilar (Mab)/polyethyleneglycol (PEG)-conjugated small gold nanoparticles (core size: approximately 5 nm) as novel platform (Mab) delivery. Mab/PEG-conjugated were successfully prepared, and the particles characterized by transmission electron microscopy dynamic light scattering method. The mean diameters PEG-conjugated varied using different lengths PEG chain (5 kDa 10 kDa). Mab conjugation efficiency was optimized changing amount in preparation, which showed high (>70%). We found that effectively inhibited tube formation human umbilical vein endothelial cells based on Matrigel in vitro . without unexpectedly. did not affect cell proliferation cells. These results suggest can be used good colloidal formulation angiogenesis-related diseases local sites such
