“…NPs can be synthesized using various methods, but some involved the use of hazardous and poisonous substances that provide a high risk of toxicity (Khan et al 2019 ). Green synthesis is one of the most environmentally friendly and low-cost approaches with high reproducibility and yield (Hano and Abbasi 2022 ). Apart from the use of bacteria, fungi, and algae, aqueous extracts of leaves have been found to reduce silver salt and instantly capped the nanosized silver to reduce agglomeration (Ansar et al 2020 ).…”

This study emphasizes the production of eco-friendly silver nanoparticles from a medicinal plant extract of Morinda lucida (M. lucida) and investigated its antioxidant and antimicrobial activity. Phytochemical screening of M. lucida (ML) leave extract was carried out and observed to contain some fundamental phyto-reducing agents such as reducing sugar, proteins, and alkaloids. The green synthesized AgNPs (ML-AgNPs) were characterized by UV–vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), transmission emission microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and Energy dispersive X-ray analysis (EDX). Thermo gravimetric analysis (TGA) was performed on the synthesized ML-capped AgNPs to determine the thermal stability and the formation of the green synthesized AgNPs. The formation of AgNPs was confirmed by the UV–vis absorption spectra, which showed an absorption band at 420 nm. The morphology of ML extract-mediated AgNPs was mostly spherical and rough-edged crystallite nanostructures, with an average particle size of 11 nm. The FTIR analyses revealed distinctive functional groups which were directly involved in the synthesis and stability of AgNPs. The crystallite size was 8.79 nm, with four intense peaks at 2 θ angles of 38°, 44°, 64°, and 77°. At an energy level of 3.4 keV, a significant signal was observed indicating the production of thermally stable and pure crystallite AgNPs. The antioxidant property of green synthesized ML-AgNPs was determined to be 40% higher than that of crude M. lucida leaf extract. The ability of green synthesized ML-AgNPs to scavenge free radicals also increased in the order of OH − < NO < H 2 O 2 . The ML-AgNPs have strong activities with a maximum against P. vulgaris and a minimum with E. faecalis.

“…Phytochemicals that exist in plant such as amino acid, proteins, vitamins, organic acid and secondary metabolites such as phenols, flavonoids, terpenoids and alkaloids are responsible for reducing metal oxide nanoparticles and capping them 24,25,26 .For Eucalyptus leave, it was found different types of biomolecules such as polyphenolic components, terpenoids and tannins can reduce Fe ions 27,28,29 ,in addition to proteins, alkaloids and small amount of fructose and glucose can be responsible for stability of produced nanoparticles. 30,31 Phytochemicals that exist in pomegranate leave can reduce metal oxide and stabilize the produced nanoparticles like polyphenols, punicalin, punicafolin, flavones glycosides, luteolin and apigenin 32,33,34 .In the same case for oolong tea extract contains polyphenols, flavonoids,catechins, lignin and terpenoid play important role as reducing and stabilizing agent 35,36,37 .…”

Three plants extracts of Eucalyptus, Pomegranate and Oolong tea leaves have been used to synthesize iron oxide nanoparticles. The structure and particle size of the nanoparticles have been investigated by XRD spectrum. The results exhibit the polycrystalline nature of the material with a size around (17-19 nm). FESEM analysis showed that using different extracts as a reduction and capping agent might affect the shape of nanoparticles such as forming of round, polygon and irregular shapes under the same conditions. The photo catalyst activity of the prepared NPs in the degradation of MB dye has been investigated. the results showed a good efficiency reached to 91%, 88% and 80%.

“…The growing demand for green chemistry and nanotechnology has pushed for the development of green synthetic methods for the production of nanomaterials using plants, microbes, and other natural resources. Catalysis, medicine, cosmetics, agriculture, food packaging, water treatment, dye degradation, textile engineering, bioengineering sciences, sensors, imaging, biotechnology, electronics, optics, and other biological sectors are just some of the potential applications of these green plant-based NPs [93]. The type and biomedical application of various NPs derived from different kinds of plants are shown in Table 1.…”

Engineering, physics, chemistry, and biology are all involved in nanotechnology, which comprises a wide variety of multidisciplinary scientific field devices. The holistic utilization of metallic nanoparticles in the disciplines of bio-engineering and bio-medicine has attracted a great deal of attention. Medical nanotechnology research can offer immense health benefits for humans. While the advantages of developing nanomaterials have been well documented, it is precisely apparent that there are still some major issues that remain unattended to those need to be resolved immediately so as to ensure that they do not adversely affect living organisms in any manner. The existence of nanoparticles gives them particular value in biology and materials science, as an emerging scientific field, with multiple applications in science and technology, especially with numerous frontiers in the development of new materials. Presented here is a review of recent noteworthy developments regarding plant-derived nanomaterials and their use in the development of medicine and biomedical applications around the world.
