Green synthesis of nanoparticles is the method with eco-friendly, cost-effectiveness, and ease of resource availability approach. Nowadays, magnetic nanoparticles need increased due to its use in magnetic sensing, medical imaging, waste water treatment, and antibiotic drugs. In this report, the ecofriendly green synthesis of magnetic iron oxide nanoparticles were efficiently synthesized by using Murraya koenigii leaves extract. UV-visible spectrum revealed the surface Plasmon resonance band at 240 nm and analyzed the formation of iron oxide nanoparticles. X-ray diffraction pattern determined its high crystalline nature with strong intense peaks. Fourier Transform Infra-Red spectrum illustrated the Fe and O bonding stretching vibration. The particle size distribution graph showed the formed particles are in nanometer range. Transmission Electron Micrographs realized the spherical shaped iron oxide nanoparticles with its size at 10–25 nm. The energy dispersive X-ray spectrum and mapping analysis revealed the purity of prepared nanoparticles with only Fe and O presence. The vibrating sample magnetometer analysis showed the paramagnetic behavior of prepared magnetic iron oxide nanoparticles. The antimicrobial assay revealed potent inhibition of iron oxide nanoparticles on various human pathogens. The antioxidant, anti-inflammatory and anti-diabetic assays revealed the biomedical behavior of iron oxide nanoparticles.

In this report, ZnO nanoparticles were biosynthesized using Paspalum scrobiculatum grains extract for the first time. GC–MS analysis explicated that diethyl phthalate was the major phytocompound with 94.09% in aqueous extract. ZnO nanoparticles formation was confirmed by various physicochemical analyses. HR‐TEM images showed the hexagonal, rectangular shaped nanoparticles in 15–30 nm size. The antioxidant, anti‐inflammatory, and anti‐diabetic analyses showed the effective bioactivity of ZnO nanoparticles in 80 μg/ml concentration with 95.36%, 94.08%, and 91.96%, respectively. The morphological and tissue changes witnessed in larvicidal and insecticidal activities against Culex tritaeniorhynchus and Tribolium castaneum revealed the efficient nature of ZnO nanoparticles in 100 ppm at 48 h and 100 μg/kg at 72 h, respectively. The morphological changes in antibacterial activity demonstrated the bactericidal nature of ZnO nanoparticles against Salmonella typhi and Staphylococcus aureus in 150 μg/ml concentration. The morphological observations in anticancer activity against HepG2 liver cancer cells showed the potent drug features of ZnO nanoparticles in 100 μg/ml concentration with 97.18% of cytotoxicity. The ZnO nanoparticles showed no toxicity against HDF normal cells in lower concentrations and it explicated the biocompatible features of nanoparticles. The Vigna radiata plant growth was efficiently promoted by low (60 ppm) concentration of nanoparticles. The ZnO nanoparticles divulged effective degradation of IPA, EDTA, BQ, and DPBF in 75%, 45%, 55%, and 80% through ROS formation, respectively. Thus, the synthesized ZnO nanoparticles are biocompatible and inexpensive material compared to the traditional one and can be utilized as an efficient material in biological fields. Research Highlights Efficient larvicidal and insecticidal activities were evinced at low IC50 value. The ZnO nanoparticles were non‐toxic to HDP (fibroblast) normal cells. Efficient plant growth was attained at 60 ppm concentration.
