Abstract In the present study, zinc oxide nanoparticles were obtained by combustion. Zinc nitrate salt was used as oxidizer and urea, glycine and the combination of urea and glycine together were used as fuel. In order to eva‎luate the effect of fuel type, zinc oxide was processed with three different fuel types (urea, glycine, urea and glycine combination). The structure and particle size of the synthesized oxide surface powders were examined by X-ray diffraction and electron microscopy. Zinc oxide doped with europium oxide was calcined at 800 ° C and the properties were investigated and then the zinc oxide powder produced was used to make a polymer-based composite with chitosan and polylactic acid. Composite samples were produced in different percentages of the above materials by 3D printer and slurry casting method. The properties, morphology and particle size of the samples were investigated by XRD, FESEM and EDX analysis and the optical properties of zinc oxide were processed by photoluminescence analysis. Pl) was checked. In order to investigate the biomaterial applications of the produced composite, the samples were subjected to biocompatibility testing in body simulation solution. The results of the analyzes showed that it is possible to obtain zinc oxide nanoparticles with hexagonal structure, high fuzzy purity and create the expected porosity in the samples. High purity was obtained.
