Abstract
Copper oxide nanoparticles were successfully synthesized through a simple and ‘green’ route using starch as a capping and stabilizing agent under ultrasonic irradiation in alkaline medium.Unique reaction condition was prepared by ultrasonic irradiation, releasing the stored energy in the collapsed bubbles and heats the bubble contents that leads to Cu(II) reduction in the presence of starch. The obtained nanoparticle (CuO NPs@Starch) was characterized by advanced physical and chemical techniques like Transmission Electron Microscope (TEM), Fourier-transform infrared spectroscopy (FTIR), Uv–Vis spectroscopy, scanning electron microscopy (SEM), X-ray Diffraction (XRD) and energy-dispersive X-ray analysis (EDX). The properties of CuO NPs@Starch against gastric cancer (AGS and KATO III), pancreatic cancer (AsPC-1 and MIA PaCa-2), and colon cancer (HCT 116 and HCT-8) were evaluated. The viability of malignant cancer cell lines reduced dose-dependently in the presence of CuO NPs@Starch. After clinical study, CuO NPs@Starch can be utilized as an efficient drug in the treatment of gastric, pancreatic, and colon cancers in humans.
