As global food security faces challenges, enhancing crop yield and stress resistance becomes imperative. This study comprehensively explores the impact of nanomaterials (NMs) on Gramineae plants, with a focus effects various types nanoparticles, such as iron-based, titanium-containing, zinc, copper plant photosynthesis, chlorophyll content, antioxidant enzyme activity. We found that nanoparticles largely depend their chemical properties, particle size, concentration, species developmental stage plant. Under appropriate conditions, specific NMs can promote root development enhance increase content. Notably, iron-based titanium-containing show significant in promoting synthesis growth. However, oxidative is complex. certain plants’ activity, improving ability to withstand environmental stresses; excessive or inappropriate may cause stress, affecting growth development. Copper particular, exhibit this dual nature, being beneficial at low concentrations but potentially harmful high concentrations. provides theoretical basis for future nanofertilizers aimed precisely targeting plants capacity improve photosynthesis efficiency. emphasize importance balancing agricultural advantages nanotechnology safety practical applications.

Xenobiotic pollution in environment is a potential risk to marine life, and human health. Nanobiotechnology an advanced emerging solution for the removal of environmental pollutants. Adsorption-based technologies are being used alleviate global prevalence xenobiotics like dyes, due their high efficacy cost effectiveness. Current study explored nanobiochar syntehsized via ultrasonication centrifugation from rice husk dye water. It involves synthesis biochar Safranin, Malachite green, mixture both aqueous Biochar was synthesized through pyrolysis at 600 °C 2 h. To convert it into nanobiochar, sonication techniques were applied. The yield obtained 27.5% 0.9% nanobiochar. Nanobiochar analysis Fourier-Transform Spectrometer (FTIR), X-ray Power Diffraction (XRD) scanning electron microscopy (SEM) suggested its crystalline nature having minerals rich silicon, with cracked disintegrated carbon structure temperature processing treatments. Removal dyes by evaluated changing different physical parameters i.e., dose, pH, temperature. Pseudo-first order model pseudo-second applied studying adsorption kinetics mechanism. Kinetics followed suggesting process chemical sorption. High found higher concentration temperature, neutral pH. Maximum elimination percentages safranin, malachite as 91.7%, 87.5%, 85% respectively. We conclude that could be media.
