“…Figures 2A,B show the surface morphologies of the Semal-ZnO NPs under different magnifications; the SEM images show that most of the Semal-ZnO NPs are spherical and have a synthesized diameter range of 5–35 nm. The green Semal-ZnO NPs are also found to be aggregated and homogeneous owing to the stacking morphology ( Abdelbaky et al, 2022 ; Purkait et al, 2023 ; Sreelekshmi et al, 2023 ; Supin et al, 2023 ). The agglomerated particles indicate larger sizes with low surface-to-volume ratios.…”

This work successfully demonstrates a sustainable and environmentally friendly approach for synthesizing Semal-ZnO nanoparticles (NPs) using the aqueous leaf extract of Bombax ceiba L. These NPs exhibit an absorption peak at approximately 390 nm in the UV-visible spectrum and an energy gap (Eg) of 3.11 eV. Detailed analyses of the morphology and particle size using various spectroscopic and microscopic techniques, XRD, FE-SEM with EDS, and HR-TEM reveal crystallographic peaks attributable to the hexagonal phase, with an average crystal size of 17 nm. The Semal-ZnO NPs also exhibit a notable photocatalytic efficiency for degrading methylene blue (MB) and methyl orange (MO) under sunlight in different water samples collected from diverse natural sources, indicating that they are promising photocatalysts for environmental remediation. The photocatalytic efficiency of the biofabricated Semal-ZnO NPs is impressive, exhibiting a photodegradation rate of up to 99% for MB and 79% for MO in different water samples under exposure to sunlight. The novel phytofabricated Semal-ZnO NPs are thus a beacon of hope for the environment, with their desirable photocatalytic efficiency, pseudo-first-order kinetics, and ability to break down noxious dye pollutants in various aquatic environments.

“…Lower levels of water absorption occur when the electrostatic repulsion between carboxylate groups is reduced. Additionally, the fact that there are more hydrogen bonding connections between carboxylate groups, which implies a larger physical crosslinking, may be the cause of the hydrogel films' lower capacity to absorb water [37].…”

Due to their enhanced antibacterial activity and minimal cytotoxicity, nanocomposite hydrogels have been considered attractive materials for biomedical applications. Maleic acid was used as a crosslinker in the development of methylcellulose/PVP/ZnO nanocomposite hydrogels. FESEM, FTIR, EDX, hemolytic and antioxidant tests were carried out to evaluate the prepared nanocomposites. FESEM and EDX measurements confirmed the presence of ZnO nanoparticles in the polymer matrix. The DLS revealed testing that the particle's maximum diameter is 50.7 nm, confirming the particle size and stability of the biogenic ZnO NPs. ZnO NPs incorporated nanocomposites exhibited excellent biodegradability and enhanced antioxidant activity. MC/PVP/ZnO nanocomposites exhibited a significant zone of inhibition against E. coli and S. aureus bacteria. The results showed that the prepared nanocomposites have high porosity (>80%), swelling properties, and antioxidant activity (>35%). The hemolytic activity test demonstrates that the developed nanocomposites are nontoxic. These findings significantly support the use of these innovative MC/PVP/ZnO bio-nanocomposite dressings for wound healing applications.

Nanotechnology is a fast-expanding area with a wide range of applications in science, engineering, health, pharmacy, and other fields. Among many techniques that are employed toward the production of nanoparticles, synthesis using green technologies is the simplest and environment friendly. Nanoparticles produced from plant extracts have become a very popular subject of study in recent decades due to their diverse advantages such as low-cost synthesis, product stability, and ecofriendly protocols. These merits have prompted the development of nanoparticles from a variety of sources, including bacteria, fungi, algae, proteins, enzymes, etc., allowing for large-scale production with minimal contamination. However, nanoparticles obtained from plant extracts and phytochemicals exhibit greater reduction and stabilization and hence have proven the diversity of properties, like catalyst/photocatalyst, magnetic, antibacterial, cytotoxicity, circulating tumor deoxy ribo nucleic acid (CT-DNA) binding, gas sensing, etc. In the current scenario, nanoparticles can also play a critical role in cleaning wastewater and making it viable for a variety of operations. Nano-sized photocatalysts have a great scope toward the removal of large pollutants like organic dyes, heavy metals, and pesticides in an eco-friendly and sustainable manner from industrial effluents. Thus, in this review article, we discuss the synthesis of several metal nanoparticles using diverse plant extracts, as well as their characterization via techniques like UV–vis (ultraviolet–visible), XRD (X-ray diffraction), SEM (scanning electron microscopy), TEM (transmission electron microscopy), FTIR (Fourier transform infrared spectroscopy), etc., and catalytic activity on various hazardous systems.
