“…The cell viability of the A549 lung cancer cell line was determined through mitochondrial centered activity via MTT assay. The MTT (3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyl tetra azolium bromide) salt was taken up by the cells, which were then reduced by the mitochondrial enzyme succinate which hydrogenizes to formazen and this was used to evaluate cell viability by the colorimetric method . A549 cancer cell lines exposed to the obtained ZnO NRs go through mitochondrial damage or cellular death due to the fact of lower particle size and more number of particles entered into the cells resulting in the formation of higher oxidative stress leading to cellular apoptosis …”

The tunable ZnO nanorods (NRs) are produced due to the phytochemicals present in Cycas pschannae leaves which act as reducing and stabilizing agents. The confirmations of the ZnO NRs were validated using different characterization techniques: X‐ray diffraction, Fourier transform infrared spectroscopy, Brunauer, Emmett and Teller (BET), scanning electron microscopy–Energy Dispersive X‐Ray Analysis (EDX), UV–visible spectroscopy, Raman spectroscopy, and transmission electron microscopy. The ZnO NRs show unique surface area and low particle size. Photocatalytic activity was measured and found to be 50.75% at low concentrations and 78.33% at high concentrations. The antioxidant activity of the ZnO NRs also showed promising results for their use in free radical scavenging. In vitro toxicity studies using zebrafish embryos was performed to evaluate the toxic nature of it and the obtained result confirmed its non‐toxic nature. In addition, ZnO anticancer potential was verified using the A549 lung cancer cell line. Cytotoxic assessments of ZnO NRs were performed via 2,3‐bis‐(2‐methoxy‐4‐nitro‐5‐sulfophenyl)‐2H‐tetrazolium‐5‐carboxanilide (XTT), 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyl tetrazolium bromide (MTT), and neutral red uptake assays to examine the cell death cycle on the A549 lung cancer cell. Dose‐dependent apoptosis and necrosis were confirmed by Lactate dehydrogenase (LDH) assay. It was also confirmed that ZnO NRs induce Reactive oxygen species (ROS) and apoptosis inside cancer (A549) cells via different intrinsic gene expression. Thus, based on this research it is evident that an effective ecofriendly, nontoxic potential anticancer drug can be synthesized using C. pschannae leaf extract.

“…Similarly, the enhancement of flavonoids production was reported by some researchers after treating plants with nanoparticles [61,62,63]. A study on maize by Suriyaprabha et al [64] demonstrated how silver nanoparticles significantly affect phenol and flavonoid content. Lipid peroxidation, CAT activity and oxidative stress (H2O2 production) are the causes of this increase.…”

In biosynthesis of metal nanoparticles, it is possible to replace the old chemical synthesis methods with new environment-friendly procedures. In this study, AgNP was synthesized using extracts of Rosmarinus officinalis L. leaves, and then its effect on biochemical characters, antioxidant enzymes activity, and finally carnosic acid content was studied with its various concentrations. UV-visible spectroscopy was utilized to identify the formation of synthesized AgNP. Synthesized AgNP was confirmed the absorption maxima at 500 nm wavelength. Synthesized AgNP were measured using SEM and showed 21 nm at size and spherical shape. Application of various concentrations of synthesized AgNP demonstrated the concentration dependency so that, in concentration of 40 and 60 mM of synthesized AgNP, dry and fresh weight increased. Application of synthesized AgNP at 40 mM resulted in increase of chlorophyll amount which caused more activity in anti-oxidant enzymes and also biomass accumulation such as soluble carbohydrate and flavonoid. After treatment of synthesized AgNP at 40 mM concentration, HPLC demonstrated an increase in carnosic acid. Here, small nanoparticles revealed increased in secondary metabolites. Synthesized nanoparticles can also be utilized in order to produce natural products and plants with faster growth rates.

“…A strong association was found between uptake of Si and nitrogen, phosphorus, and potassium as significant nutrients in plant growth. A comparison study focusing on the particle size of silicon to enhance the growth of maize revealed silicon enhanced silicon uptake and elongated root, making the plant resist stress conditions like decreased water supply [143]. Foliar spray contained nanosilicon and was applied to maize plants at 20day intervals and enhanced root, yield, quality, and plant growth compared with bulk silicon [144].…”

Agriculture waste has attracted attention as a potential source to produce raw material silicon dioxide, either crystalline (pyrophyllite) or amorphous form (geothermal sludge). It is an unwanted waste produced as a desired result of agricultural activities. Nanosilicon dioxide has undoubtedly gained eager interest in many vital industries. It is renowned for positively enhancing outstanding performance due to tuneable properties over its bulk counterpart. Silicon dioxide scientifically demonstrates a unique ability to convert efficiently into economic value from silicon-rich agriculture waste. Thus, a noble extraction from silicon-rich waste is undoubtedly gaining enormous attention. However, adequate knowledge on local optimisation of nanosilicon dioxide extraction from silicon-rich agriculture waste is lacking. Specific aims of this comprehensive review mainly highlighted a synthesis method of potential nanostructured silicon dioxide from agriculture waste and their potential applications for plant growth promoters. Reverse microemulsion, chemical vapour condensation, solid gelation, and mechanochemical are preferred methods that were typically specified to focus this comprehensive review critically. Optimisation of nanosilicon dioxide can be achieved precisely via the ideal combination of solid gelation and a high-energy ball mill process. Silicon dioxide is undoubtedly an effective agent as a plant growth promoter to overcome biotic and abiotic factors such as heavy metal uptake and translocation, inhibit pathogenic fungi, improve the antioxidant system, and mitigate various stress factors.
