Gold nanoparticles are biocompatible and are having several applications in biomedical Sciences and Engineering. Integration of nanoscience in medicine leads to the development of biomedical products that helps the Society in a faster and safer manner. In the present research work, bioreduction and biofunctionalization of gold nanoparticles are performed with fruit extracts of Aegle marmelos, Eugenia jambolana and soursop. The nanoparticles are characterized using UV-Vis spectroscopy, Transmission Electron Microscopy, Fourier Transform Infrared Spectroscopy and Zeta potentiometer. The qualitative phytochemical analysis of the fruit extracts shows the presence of alkaloids, amino acid, flavonoids, phenol, proteins, tannin, reducing sugars and total Sugars. The in vitro anticancer activity was confirmed by MTT assay on the human breast cancer cell line MCF-7 at different concentrations. The flavonoids present in the fruit extracts are potential reducing agent which is responsible for the formation of gold nanoparticles. Stabilization of gold nanoparticles are performed by the carboxylate group present in the proteins. Also, the nanoparticles are held apart from each other by the electrostatic repulsions that exist due to the presence of like charges surrounding the gold nanoparticles. This study proves that the fruit extracts can be used for the synthesis and stabilization of gold nanoparticles. Further, the engineered nanoparticles capped with bioactive compounds are potential anticancer agents against breast cancer cell line MCF-7. (C) 2019 King Saud University.
