This article examines the synthesis of silver nanoparticles utilizing Sansevieria Zeylanica leaf extract (SZ-AgNPs) as a green stabilizing and reducing agent. The biosynthesized SZ-AgNPs exhibit distinct properties, characterized by a well-defined morphology and size, as validated through UV-Vis spectroscopy, X-ray diffraction, and scanning electron microscopy analyses. The research investigates the potential applications of eco-friendly obtained SZ-AgNPs in environmental remediation, with a particular focus on their catalytic performance in degrading synthetic dyes, notably crystal violet and Congo red. Furthermore, the antimicrobial activity of the SZ-AgNPs is assessed against various bacterial and fungal strains. The findings reveal substantial dye degradation percentages and significant zones of inhibition against both gram-positive bacteria, underscoring the dual advantages of environmentally friendly nanoparticle synthesis for sustainable applications in wastewater treatment and antimicrobial interventions. The study underscores the pivotal role of green nanotechnology in tackling pressing environmental challenges, advocating for the adoption of eco-friendly approaches in nanoparticle synthesis for a more sustainable future.

“…Among metal nanoparticles, zinc oxide (ZnO) is of much interest to researchers and the scientific community owing to its excellent properties in environmental sustainability. ZnONPs are biosynthesized via a very simple procedure using various plant extracts such as Lemna minor [ 5 ], thyme [ 6 ], Delonix elata [ 7 ], Aloe vera [ 8 ], and Pongamia pinnata [ 9 ]. This biosynthesis procedure does not require any additional external chemical stabilizers, as the biochemical compounds present in the plant extract can act as reducing and stabilizing agents for the synthesis [ 10 ].…”

The implementation of nanotechnology in the field of plant tissue culture has demonstrated an interesting impact on in vitro plant growth and development. Furthermore, the plant tissue culture accompanying nanoparticles has been showed to be a reliable alternative for the biosynthesis of secondary metabolites. Herein, the effectiveness of zinc oxide nanoparticles (ZnONPs) on the growth of Delonix elata calli, as well as their phytochemical profiles, were investigated. Delonix elata seeds were collected and germinated, and then the plant species was determined based on the PCR product sequence of ITS1 and ITS4 primers. Afterward, the calli derived from Delonix elata seedlings were subjected to 0, 10, 20, 30, 40, and 50 mg/L of ZnONPs. The ZnONPs were biologically synthesized using the Ricinus communis aqueous leaf extract, which acts as a capping and reducing agent, and zinc nitrate solution. The nanostructures of the biogenic ZnONPs were confirmed using different techniques like UV–visible spectroscopy (UV), zeta potential measurement, Fourier transform infrared spectra (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Adding 30 mg/L of ZnONPs to the MS media (containing 2.5 µM 2,4-D and 1 µM BAP) resulted in the highest callus fresh weight (5.65 g) compared to the control and other ZnONP treatments. Similarly, more phenolic accumulation (358.85 µg/g DW) and flavonoid (112.88 µg/g DW) contents were achieved at 30 mg/L. Furthermore, the high-performance liquid chromatography (HPLC) analysis showed significant increments in gallic acid, quercetin, hesperidin, and rutin in all treated ZnONP calli compared to the control. On the other hand, the gas chromatography and mass spectroscopy (GC-MS) analysis of the calli extracts revealed that nine phytochemical compounds were common among all extracts. Moreover, the most predominant compound found in calli treated with 20, 30, 40, and 50 mg/L of ZnONPs was bis(2-ethylhexyl) phthalate, with percentage areas of 27.33, 38.68, 22.66, and 17.98%, respectively. The predominant compounds in the control and in calli treated with 10 mg/L of ZnONPs were octadecanoic acid, 2-propenyl ester and heptanoic acid. In conclusion, in this study, green ZnONPs exerted beneficial effects on Delonix elata calli and improved their production of bioactive compounds, especially at a dose of 30 mg/L.
