Description
Summary:[Display omitted] •Astaxanthin (Ast) coated ZnO and CeO2 NPs were synthesized and characterized.•Ast:ZnO and Ast:CeO2 NPs shows the good absorbance band in UV region.•Ast:ZnO and Ast:CeO2 NPs were hexagonal rod shaped and small particles with network like structure.•Ast:ZnO and Ast:CeO2 NPs exhibited good inhibition zone against bacteria and fungi. ZnO and CeO2 nanoparticles (NPs) are synthesized using Chamaecostus cuspidatus extract by greener route. Synthesized ZnO and CeO2 NPs were coated with astaxanthin as synthesized Ast:ZnO and Ast:CeO2 NPs retained the hexagonal wurtzite structure and cubic structure, which were confirmed by XRD studies. FESEM images revealed Ast:ZnO and Ast:CeO2 NPs were nano-rod and sphere-shaped structure. Chemical compositions were recognized by using EDAX analysis. FT-IR and Raman spectra confirmed the stretching bands for Ast:ZnO and Ast:CeO2 NPs. UV–VIS absorption spectra, the absorption edges peak was observed at 360 nm and 309 nm for Ast:ZnO and Ast:CeO2 NPs respectively. Antimicrobial activities were carried out against a set of bacterial and fungal strains for the AST: ZnO and Ast:CeO2 NPs using Chamaecostus cuspidatus leaf extract. Anticancer properties are studied with human breast cancer cell line (MCF 7) using Ast:ZnO and Ast:CeO2 NPs.
