A G 4.0 dendrimer-like poly(amido amine)(PAMAM)basedon silica manoparticles was fabricated via a divergent approach.It was built from γ-aminopropyl silica nanoparticles(APSN)core via repetitive addition of acrylate(MA)and hexylenedi-amine(HDA).FT-IR and EA were used to monitor theprogress of dendrimer during each step.The amino group con-tent of the resulting product increased from 0.49 to 3.72 mmol/g after the 4th generation.In addition,the percentage of graft-ing increased with increasing generation and reached to 65.9%
