Ticks (Ixodidae and Argasidae) pose significant health risks as vectors for infectious diseases, with their prevalence expanding across Europe North America. employ sophisticated sensory mechanisms, notably utilizing Haller's organs, to locate sense hosts. These structures detect various cues, including chemosensation, changes in atmospheric CO2 concentration, radiant heat emitted by potential Once a host is detected, landing facilitated electrostatic attraction, accelerating the precise positioning of tick feeding. Reports indicate that ZnO nanoparticles exhibit acaricidal activity. The strong thermal electrical conductivity may effectively impede host-seeking mechanisms. This study focuses on fabricating ZnO-containing nanostructured polylactic acid (PLA) fiber material repellency. In this research, acetone, chosen its low toxicity compatibility natural acaricides, utilized single-solvent system produce nanofibers long-lasting properties. Successful electrospinning acetone-based systems has been limited needle electrospinning. Here, we present method employing needleless fabricate nanoparticle-loaded PLA using pike-type electrode. PLA-ZnO solutions were characterized density, conductivity, viscosity, other parameters, while resulting mats underwent analysis via FTIR, SEM, evaluation conductivity. Optimization spinning parameters critical voltage, collector distance, environmental factors such temperature humidity was conducted. Our demonstrates creation fibers single solvent through Obtained membranes contain 1-3 wt% within an 8-10 matrix solution heightened advancement underscores tick-repellent materials strategies against tick-borne diseases.
