Mosquitoes pose a threat to humans and animals, causing millions of deaths every year. Vector control by effective eco-friendly pesticides of natural origin is a serious issue that requires urgent attention. The employment of green-reducing extracts for nanoparticles biosynthesis in a rapid and single-step process represents a promising strategy. In this study, silver nanoparticles (AgNPs) were biofabricated using an essential oil of Aquilaria sinensis (AsEO) and Pogostemonis Herba essential oil of Pogostemon cablin (PcEO) in one step and cost-effective manner. UV-vis spectrophotometry, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction analysis and energy-dispersive X-ray spectroscopy were used to confirm the AgNPs formation and their biophysical characterization. The larvicidal and pupicidal toxicity of AsEO, PcEO and biosynthesized AgNPs were evaluated against larvae and pupae of the dengue and Zika virus vector Aedes albopictus. Compared to the tested essential oils, the biofabricated AgNPs showed the highest toxicity against larvae and pupae of Ae.albopictus. In particular, the LC values of AsEO ranged from 44.23 (I) to 166 (pupae), LC values of PcEO ranged from 32.49 (I) to 90.05(IV), LC values of AsEO-AgNPs from 0.81 (I) to 1.12 (IV) and LC values of PcEO-AgPNs from 0.85 (I) to 1.19 (IV). Furthermore, histological analysis of the midgut cells of the control and treated larvae exhibited that the epithelial cells and brush border were highly affected by the fabricated AgNPs compared to the essential oils (AsEO and PcEO). Overall, the A. sinensis and P. cablin essential oils fabricated AgNPs have a potential of application as a biopesticide for mosquito control through safer and cost-effective approach.

“…In terms of practical applications, silver nanoparticles (Ag-NPs) synthesized from plant extracts showed antimicrobial properties against Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, and Escherichia coli and the implementation of Ag-NPs to food packaging has been suggested (Mohanta, Panda, Bastia, & Mohanta, 2017;Soshnikova et al, 2017). Additionally, new potential application of green Ag-NPs from plant-mediated synthesis as a biopesticide has been demonstrated (Suresh et al, 2018).…”

Silver nanoparticles (Ag-NPs) were synthesized in an eco-friendly manner using aqueous Houttuynia cordata leaf extract (HLE). HLE mediated Ag-NPs (Ag-NPs/HLE) exhibited surface plasmon resonance with a maximum absorbance at 450 nm. The mean diameter of Ag-NPs was 23 nm, and their crystalline structure was confirmed via X-ray diffraction analysis. Fourier-transform infrared spectroscopy indicated that hydroxyl, carboxyl, and ketone groups of sugar or polyphenolics were involved in Ag-NPs synthesis. The contribution of reducing sugars to the reduction of Ag ions was found to be greater than that of polyphenols. NO production in LPS stimulated RAW 264.7 macrophages was more effectively inhibited by Ag-NPs/HLE than by chemically synthesized Ag-NPs. The production of the major inflammatory mediators, PGE 2 and TNF-α was decreased by 73% and 66%, respectively, upon the addition of 10 μg/mL Ag-NPs/HLE. Ag-NPs biosynthesized using HLE showed improved anti-inflammatory activity compared to conventional Ag-NPs owing to the incorporation of phytochemicals. Biosíntesis de nanopartículas de plata mediada por el extracto de hojas de Houttuynia cordata: caracterización y mejoramiento de la actividad antiinflamatoria RESUMEN En este estudio se sintetizaron nanopartículas de plata (Ag-NPs) de una forma amigable con el medio ambiente, empleando para ello el extracto acuoso de la hoja de Houttuynia cordata (HLE). Las Ag-NPs mediadas por HLE (Ag-NPs/HLE) presentaron resonancia plasmónica de superficie con una absorción máxima de 450 nm. Se constató que el diámetro medio de las Ag-NP fue de 23 nm, confirmándose su estructura cristalina mediante el análisis de difracción por rayos-X. A través de una espectroscopia infrarroja transformada de Fourier se comprobó que los grupos de azúcar hidroxilo, carboxilo y cetona o polifenólicos intervinieron en la síntesis de las Ag-NPs. Asimismo, se comprobó que la contribución de los azúcares reductores a la disminución de los iones de Ag es mayor que la de los polifenoles. La producción de NO en los macrófagos 264.7 RAW estimulados por LPS [lipopolisacáridos] fue inhibida de manera más eficaz por las Ag-NPs/HLE que por las Ag-NPs de síntesis química. Cuando se adicionaron 10 μg/mL de Ag-NPs/HLE, la producción de los principales intermediarios inflamatorios, PGE 2 yTNF-α, disminuyó en 73% y 66%, respectivamente. Las Ag-NPs biosintetizadas utilizando HLE muestran mayor actividad antiinflamatoria en comparación con las Ag-NPs convencionales, debido a la incorporación de fitoquímicos.

The synthesis of nanoparticles can be accomplished by physical, chemical and biological strategies. Since this has become an expanding area of research in the field of medical sciences and Technology, owing to its potential applications, the need for eco-friendly, non-toxic and economical methods of synthesis have arisen. Biosynthesis of nanoparticles have become the main field of research as it is time efficient, cost effective, less toxic and has abundant resource. This review emphasizes on the biosynthesis of gold (Au) and silver nanoparticles (AgNPs) using marine sources with special reference to algae, their characterisation and its applications. The characterisation of metal nanoparticles is an essential step and can be carried out by various instruments. The various pharmacological, electrical, pest management, parasitology and medical applications of these marine source induced synthesis of nanoparticles have also been portrayed in this review.Â
