Polymeric systems can facilitate the diffusion of micronutrients through seeds, offering an innovative and sustainable way to improve plant health increase food production. In present work, a polymeric nanogel based on polyether-POE-diamine bisepoxide was synthesized in-depth characterized, encompassing its morphological characteristics (by Transmission Electron Microscopy, TEM), size distribution, surface charge particles dynamic light scattering, DLS zeta potential, ζ).

In the 21st century, sustainable agriculture is expected to become a major contributor food security and improved nutrition. Amine–epoxide-based materials have great potential for use in due their tunable physicochemical features, which are dependent on concentration composition of monomers. this work, catalyst-free green synthesis, using only water as solvent, was performed obtain nanocarrier (TGel) capable transporting nutrients after seed priming. The synthesis based opening epoxy ring by nucleophile attack, an amine-terminated polyether. Transmission electron microscopy (TEM) dynamic light scattering (DLS) techniques showed spherical morphology particles, ranged size from 80 nm (unloaded TGel) 360 (zinc-loaded TGel), respectively. Theoretical bonding analysis revealed that Zn cation species ZnSO4 source interact with polymer via σ-bonds, whereas EDTA forms hydrogen bonds polymer, thereby enhancing noncovalent interactions. Micro X-ray fluorescence (μ-XRF) energy-dispersive spectroscopy (EDXRF) provided details distributions compartments shoots cucumber plants priming plant growth, Zn-loaded TGels did not affect physiology plants, indicated photosynthetic efficacy, chlorophyll, anthocyanin indices.
