ABSTRACT Mosquito‐borne diseases remain a significant health concern amidst current microbial outbreaks. Phytochemicals offer environmentally safe, biodegradable, and targeted pest management. Nanostructure lipid carriers (NLCs), second generation of solid nanoparticles, are gaining attention as potential diagnostic therapeutic tools. Sesbania leaves, rich in fatty acids, phenolics, terpenes, were analyzed using gas chromatography–mass spectrometry. Magnetic nanoparticles (Se‐NLC‐MNPs) modified the surface extract, encapsulated NLC. The resulting 129.2 218.5 nm size, with zeta potentials −6.20 43.9 mV, respectively. Transmission electron microscopy showed spherical oval shapes. XRD patterns confirmed successful decoration NLC magnetic nanoparticles. extract (Se) its nanoparticle conjugates tested for larvicidal efficacy against Culex pipiens Musca domestica larvae, at doses ranging from 50 to 1500 ppm 0.1 5 mg/mL. Se‐NLC‐MNPs higher larval mortality rates compared their Se formulation extracts, achieving 100% third‐instar larvae. methanol contained more other organic compounds than aqueous making it harmful insect In terms relative toxicity, effective Se‐NLC. An vitro cytotoxicity assay WI38 cell line indicated assay, suggesting these develop into high‐performance, acceptable therapeutics mosquito‐borne diseases.
