• . These compounds act by reducing Ag+ ions to Ag0 and stabilize nanoparticles by capping [58] (Figure 2). Larvicidal activity of AgNPs against Aedes aegypti Aedes aegypti, also known as the dengue mosquito, is a vector of important arboviruses, including Dengue, Zika, Chikungunya and Yellow Fever [6][59

• ), 26 µg/mL (L3), and 29 µg/mL (4). The treatment exposure time was not described by the authors. Gopu, et al. synthesized and investigated the larvicidal potential of AgNPs from the seaweed extract Amphiroa rigida [54]. Aedes aegypti larvae at stages L3 and L4 were treated with A. rigida AgNPs (5–80 μg

• economical, energy efficient, and environmentally friendly. The use of AgNPs synthesized from extracts of seaweed species against Aedes aegypti may be a viable option for replacing commercially available synthetic chemical insecticides, being able to surpass them in terms of larvicidal activity with lower

• Aedes aegypti larvae [7]. This warrants further investigation on eco-friendly insecticides to fight Aedes aegypti, the primary vector of dengue, zika, and chikungunya. Overall, this article collection was conceived to be an original literature resource converging nanomedicine and NTDs. All high-quality

• involving Galleria mellonella larvae. Additionally, we investigated the insecticidal efficacy of monoterpenes against the mosquito Aedes aegypti, the primary dengue vector, via larval bioassay. Employing a low-energy approach, we successfully generated nanoemulsions. The cymene-based nanoemulsion exhibited

• low toxicity towards HaCAT cells and Galleria mellonella larvae. Moreover, the nanoemulsions exhibited significant lethality against third-instar Aedes aegypti larvae at a concentration of 50 mg/L. In conclusion, the utilization of nanoemulsions encapsulating cymene and myrcene presents a promising

• are several subspecies of mosquitos, such as Aedes aegypti, that have evolved to specialize in human hosts [35]. An adapted design would be advantageous for painless transdermal delivery of macromolecules or biological sampling [38]. Adult ticks, as another example, live on their hosts for 7–10 days
