Anethum graveolens extract functions as a green reducing agent and stabilizing agent during the advanced biological synthesis process of cobalt-doped titanium oxide nanoparticles (TiO2:0.3Co). The laboratory produced nanomaterials received detailed assessment through various structural, morphological, optical and electrochemical characterization methods. The XRD analysis verified TiO2:0.3Co nanoparticles exist as highly crystalline structures with an average estimate of 29 nm for crystallite dimension. The spherical nanometer-sized particles had extensive clustering according to SEM and EDX analysis caused by nanoscale interparticle attractions. The presence of cobalt doping in the material structure reduced its optical band gap to 1.75 eV which increased its visible-light photocatalytic activity according to UV-Visible spectroscopy results. The chemical analysis through FTIR spectrometry validated metal-oxygen bond character through distinctive vibrational spectra which proved the structural stability of synthesized materials. The nanoparticles showed excellent glucose detection properties during electrochemical testing which suggests their practical use as biosensors. The extensive research shows an environmentally conscious synthesis method with high efficiency which makes TiO2:0.3Co nanoparticles suitable for environmental cleanup operations and biomedical sensing.

The study investigated effects of irradiation and nanoparticles spraying on the chemical content of borage leaves in 20 experimental groups. Each with ten replicates, categorized based on treatment type to gamma radiation, and nanoparticle spraying which were sprayed uniformly on the aerial parts of each plant at 21 days after germination. Using a fine-nozzle hand sprayer to ensure full coverage without excess. Results showed that the spraying of MgO nanoparticles at a concentration of 20 mg/L significantly increased magnesium levels (p ≤ 0.05). Reaching a peak value of 1.50 ± 0.14 mg/L compared to the control group. In the case of zinc, treatment with ZnO nanoparticles at 40 mg/L led to a modest improvement, with the highest observed concentration being 1.73 ± 0.14 mg/L. The radiation-only groups (CR1–CR3) failed to show any significant improvement in mineral levels; instead, there were notable decreases in some groups, especially at higher doses (180 Gy in CR3). Combined treatments (N1R1–N4R3) showed no significant improvement over nanoparticle spraying alone. Nanoparticle spraying alone was more effective than radiation in improving both magnesium and zinc levels. The combination of radiation and nanoparticle spraying did not yield better results than nanoparticle treatment alone, suggesting that radiation might weaken the benefits of nanoparticles in mineral uptake.
