Sustainable Green Synthesis of Yttrium Oxide (Y2O3) Nanoparticles Using Lantana camara Leaf Extracts: Physicochemical Characterization, Photocatalytic Degradation, Antibacterial, and Anticancer Potency

Abstract

Due to their appropriate physicochemical properties, nanoparticles are used in nanomedicine to develop drug delivery systems for anticancer therapy. In biomedical applications, metal oxide nanoparticles are used as powerful and flexible multipurpose agents. This work described a green synthesis of Y2O3 nanoparticles (NPs) using the sol-gel technique with the use of aqueous leaf extracts of Lantana camara L (LC). These nanoparticles were characterized with the aid of different methods, including UV, X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR), transmitted electron microscopy (TEM), and photocatalytic degradation. Y2O3 nanoparticles showed excellent antibacterial activity against Gram-positive Bacillus subtilis and Gram-negative Escherichia coli with a 10 to 15 mm inhibitory zone. Green Y2O3 NPs were released with a 4 h lag time and 80% sustained release rate, indicating that they could be used in drug delivery. In addition, the bioavailability of green Y2O3 NPs was investigated using cell viability in cervical cancer cell lines. These green-synthesized Y2O3 NPs demonstrated photocatalytic degradation, antibacterial, and anticancer properties.

“…The Y 2 O 3 NPs displayed broad UV absorption with an elevated intensity at 238 nm, as shown in Figure 1a. Similar findings were obtained for yttrium nanoparticles and rare earth oxides, 37 where the cause of the impact was absorption-induced scattering. The rGO displayed a distinctive peak at 265 nm, while GO exhibits absorbance at 225 nm.…”

Plant and Microbial Approaches as Green Methods for the Synthesis of Nanomaterials: Synthesis, Applications, and Future Perspectives

“…Meanwhile, the essential role of synthesis in the intracellular method is attributed to the cellular enzymes of different plant tissues, which later require complicated steps to attract the synthesized NMs by cracking the cell wall of the plant. Recently, aqueous leaf extracts of Lantana camara were used for the green synthesis of yttrium oxide (Y 2 O 3 ) nanoparticles ranging from 20 to 45 nm [ 80 ]. The synthesized Y 2 O 3 nanoparticles showed photocatalytic activity toward the degradation of Rhodamine B (RhB) dye under a 250 W Xenon lamp with high pressure.…”
