Stages
- 1.Nanoparticle preparation and functionalization(library_build)
This stage creates the Zn-HA/CR nanocomposite that is subsequently characterized and tested.
Selection: Preparation of zinc-substituted hydroxyapatite nanoparticles from tuna fish bone waste followed by Catharanthus roseus extract functionalization to form the nanocomposite.
- 2.Structural characterization(functional_characterization)
This stage assesses material structure before or alongside biological testing.
Selection: Structural characterization of the prepared nanocomposite, including XRD named in the source-discovery summary.
- 3.Antioxidant testing(secondary_characterization)
This stage tests the antioxidant function claimed for the nanocomposite.
Selection: DPPH assay was used to evaluate antioxidant activity.
- 4.Antibacterial testing(secondary_characterization)
This stage evaluates antibacterial performance of the nanocomposite.
Selection: Antibacterial testing was performed against Staphylococcus aureus and Escherichia coli.
- 5.Cytotoxicity testing in osteosarcoma cells(confirmatory_validation)
This stage evaluates anticancer application in a cell-based model.
Selection: MTT cytotoxicity testing was performed in MG-63/HOS osteosarcoma cells.
