Abstract In present research article, single‐step biosynthesis of magnetic iron oxide nanoparticles (IONPs) is reported by using Sapindus mukorossi (SM) fruit extract as a source reducing and capping agents. Biosynthesized spherical IONPs are characterized XRD, ATR‐IR, FE‐SEM, VSM, BET, XPS techniques. VSM analysis indicates an Ms value 30.505 emu g −1 , BET reveals specific surface area 9.691 m 2 confirms the formation Fe₂O₃. NMR, GC‐MS, HR‐MS techniques reveal biological molecules in SM including flavonoids, diterpenoids, antioxidants. These biomolecules perform dynamic role capping, stabilizing, agents to synthesize stable IONPs, bottom‐up synthesis approach. They exhibit nonantibacterial potential against both Gram‐positive ( Staphylococcus aureus, (S. aureus), Bacillus subtilis (B. subtilis) ) Gram‐negative Escherichia coli, (E. coli), Pseudomonas aeruginosa (P. aeruginosa) microorganisms. Nonantifungal different fungi Penicillium spp., Aspergillus flavus (A. flavus), Fusarium oxysporum (F. oxysporum) Rhizoctonia solani (R. solani) also observed. The biosynthesized inertness toward L929 normal fibroblast cell line, making them promising candidate for drug delivery various therapeutic diagnostic applications.

The present study investigates the algae-mediated synthesis, characterization, and H2O2 sensing ability of silver nanoparticles using Sargassum spp. extract. synthesized were spherical agglomerates exhibited an absorbance peak at 418 nm, as analyzed by FE-SEM UV–vis spectrophotometric analysis. TEM-SAED analysis interpreted size between 2 – 35 nm crystallinity corresponding to face-centered cubic (FCC) structure. This was further supported from XRD findings, which ascertained presence (111), (200), (220), (311) lattice planes. FT-IR confirmed capping algal phenolics functional groups, XPS studies. observed be highly stable in aqueous suspensions, due zeta potential value (−22.6 mV). On incubation nanoparticles, with solutions, decolorization nanoparticle solution along reduction nm. color change could utilized for detection contaminated samples. Therefore, this reveals sustainable biomass synthesizing beneficial exploited environmental applications.

Abstract Increasing concern about environmental pollution attracts researchers to develop eco-friendly, low-cost, and sustainable approaches for green biosynthesis of nanoparticles overcome pollutants. This study focuses on the synthesis ceria NPs using Spirulina platensis extract as a stabilizing reducing agent. Characterization measurements, such optical properties, X-ray diffraction, SEM, TEM, FT-IR spectroscopy, confirmed successful crystalline stable with well-defined morphological features. The calculated bandgaps energy pure ceria, CeO 2 @Sp 2:1, 1:1 were 3.3, 3.15, 2.94 eV, respectively. as-synthesized showed an excellent degradation efficacy MB dye under UV irradiation. Furthermore, high photodegradation efficiency (R% = 86.2 88.8%) than 76.4%) at certain specific conditions (pH 11, contact time 90 min, catalyst dose 0.3 g/L initial concentration 100 mg/L). isothermal constants that is well-fitted Freundlich isotherm model (R > 0.99) better Langmuir < 0.8). kinetics models revealed rapid rate dye, which follows pseudo-second-order C e values ranging from 83.33 89.29 mg/g, R 0.99. These results indicated potential applicability promising avenue developing advanced wastewater treatment applications.
