In this work, nanoplatforms based on calcium phosphate (CaP), chitosan, and gold nanoparticles, as well as nanoemulsions based on nonionic surfactants, are studied for the delivery of biologically active compounds, including double-stranded RNA (dsRNA), into a plant cell. Using atomic force microscopy, the morphological characteristics of the carriers, the nature of the arrangement on graphite and mica substrates, and the geometric dimensions were evaluated to further assess their ability to form complexes with dsRNA. The project is aimed at searching for nanoplatforms of various chemical nature to create composites with biologically active RNA, which ensure the safety of molecules during exogenous application (plant spraying) and increase the efficiency of their delivery to plant leaves to protect plants from pathogens (viruses).
