Bio-inspired synthesis of chitosan/copper oxide nanocomposite using rutin and their anti-proliferative activity in human lung cancer cells.

Polymer functionalized metal oxide nanocomposites are great interest due to wide range of application, especially in nanomedicine. The present study reports an eco-friendly bio-inspired synthesis of chitosan/copper oxide (CS-CuO) nanocomposite for the first time using rutin. The bio-synthesized CS-CuO nanocomposite was characterized using UV-Visible spectroscopy, FE-SEM, EDS, TEM, XRD and FTIR analyses.

Synthesis and characterization of chitosan/iron oxide nanocomposite for biomedical applications.

The structural and optical properties of metal oxide nanoparticles exhibit remarkable changes when coated with organic polymers. In this work, we report the preparation of chitosan (CS) coated iron oxide nanocomposite using rutin by a facile greener route. The formation of iron oxide nanoparticles (FeO NPs) and CS coated iron oxide nanocomposite (CS-FeO) were preliminarily confirmed by color change and UV-Visible spectroscopy.

Preparation of chitosan coated zinc oxide nanocomposite for enhanced antibacterial and photocatalytic activity: As a bionanocomposite.

The surface coating of metal oxide nanoparticles using biopolymer chitosan has evolved to become an important area of polymer nanotechnology. Herein, we report the preparation of chitosan coated zinc oxide (CS-ZnO) nanocomposite for the first time by a green chemistry approach using bioflavonoid rutin. The formation of CS-ZnO nanocomposite was preliminarily confirmed by color change and UV-Visible spectroscopy.

Synthesis, characterization and antibacterial activity of hybrid chitosan-cerium oxide nanoparticles: As a bionanomaterials.

The hybrid chitosan cerium oxide nanoparticles were prepared for the first time by green chemistry approach using plant leaf extract. The intense peak observed around 292nm in the UV-vis spectrum indicate the formation of cerium oxide nanoparticles. The XRD pattern revealed that the hybrid chitosan-cerium oxide nanoparticles have a polycrystalline structure with cubic fluorite phase.
