A novel nanosphere based on carboxylated GO (GO-COOH) and hydroxypropyl-beta-CD (HP- β -CD) was synthesized to construct a complex of GO-COO-HP- β -CD. The complex formation process was studied using spectral characterization and transmission electron microscopy (TEM). X-ray diffraction and energy dispersive spectroscopy patterns show that HP- β -CD molecules either cover or intercalate into GO-COOH interlayers in the complex. Fourier transform infrared spectroscopy results indicate that GO-COOH and HP- β -CD are linked with covalent bonds formed via esterification. When employed as nanohybrid drug carriers for dexamethasone, the inclusion displays good dispersibility validated by dynamic light scattering (DLS). Cytotoxicity assays and hemolysis testing demonstrate that the nanospheres possess good biological compatibility. The loading capacity of dexamethasone is as high as 32.33%, with loading efficiency 64.66%.
