Description 565-574
The present research focused on the green, non-toxic, low-cost synthesis of zinc oxide nanoparticles (ZnO NPs) using
aqueous extract of Hibiscus tiliaceus leaves as a reducing and stabilizing agent. Thus, synthesized ZnO NPs were
characterized by nanotechnological applications, i.e., ultraviolet-visible spectroscopy (UV-vis), dynamic light scattering
(DLS), zeta potential, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and high-resolution
transmission electron microscopy (HR-TEM). The nanotechnological applications showed that as-synthesized ZnO NPs
have bandgap energy of 2.97 eV, zeta potential of 􀵆1.2 mV, crystalline in nature (JCPDS data card no-89-1397), and an
average size of 30 to 60 nm. The FTIR showed that ZnO NPs have coated with plant secondary metabolites and assisted in
the process of green synthesis. The ZnO NPs exhibited broad-spectrum antibacterial activity on Gram-positive and Gramnegative
bacteria. The ZnO NPs showed potential anticancer activity against human breast cancer cells MCF-7 and
determined the IC50 value as 65.83 ± 2.57 μg/mL by MTT assay. Furthermore, ZnO NPs were used as nano-catalyst for dye
degradation of methylene blue, methyl orange, and malachite green with NABH4 as a reducing agent. The ZnO NPs
exhibited potent dye degradation capability and followed pseudo-first order kinetics. The study concluded that ZnO NPs
could be highly useful as anticancer and antibacterial agents in the biomedical field, and as an environmental cleaning agent
for dye degradation in textile industries.
