Studying the Optical and Structural Properties and Anticancer Activity of New PVA–Fe2O3:Cu Nanocomposite Materials

Abstract

The purpose of this study is to evaluate the structure, morphology and optical properties of a newly developed hybrid structure that was generated from a Fe2O3–Cu–PVA composite matrix. Several methods, such as field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), as well as absorption and transmission spectra, were used to investigate the samples. The addition of copper was found to have no influence on the crystalline arrangement of PVA–Fe2O3, according to the findings of crystallography. In the wavelength region from 450[Formula: see text]nm to 550 nm, the produced composites exhibit significant absorption. It is essential that the region of shorter wavelengths experiences a steady shift toward the region of maximum absorption in these composites when copper is included. The transmittance of PVA–Fe2O3 is over 80% in the region of 600–800[Formula: see text]nm, making it an extremely transparent material. Following the addition of 5% by weight of copper to the nanocomposite, the transmittance of the material dropped to 50% within the same range of wavelengths. The synthesized materials were put to use as anti-cancer cells, and they demonstrated a high level of effectiveness in the process of killing tumor cells, particularly the PVA–Fe2O3–Cu combination.
