Cockroach wings-promoted safe and greener synthesis of silver nanoparticles and their insecticidal activity

Nickel-doped cerium oxide nanoparticles: biosynthesis, cytotoxicity and UV protection studies

“…17 The biosynthesis of nanoparticles using natural resources is a modern method with a lower expense and reduced pollution compared to previous methods. [18][19][20][21][22][23][24][25][26][27][28] Salvadora Persica (Salvadoraceae) is a tree with 6-7 m height, and its bark is cracked and wrinkled. It is an indigenous tree of the Middle East, Asia and Africa that commonly grows on the path of ooding and river bank.…”

Leishmanicidal activities of biosynthesized BaCO3 (witherite) nanoparticles and their biocompatibility with macrophages

“…Generally, various physicochemical approaches are deployed for the synthesis of barium carbonate nanoparticles; among the main disadvantages of these methods are the use of expensive equipment, toxic precursors, several reducing/stabilizing agents in a single synthesis with time-consuming and low-efficiency production [29]. On the other hand, plant extracts with low/nontoxicity can act as reducing and stabilizing agents [10,22,26,44]; nanomaterials can be fabricated via simple [3] and low-cost approaches [25,27] into various morphologies [4,31,33] using plant extracts [11,16,17,20,28].…”

Calcium carbonate nanowires: greener biosynthesis and their leishmanicidal activity

“…28,29 In the meantime, antibacterial, antivirals, and anti-parasitic properties of nanomaterials have been extensively investigated due to their favorable physicochemical properties. [30][31][32][33][34][35][36][37][38] So far, the anti-leishmanial activity of various nanomaterials such as silver, zinc oxide, liposomes, titanium oxide has generated positive results but the calcium carbonate nanostructures have not been studied although calcium nanostructure have been considered in various elds due to their non-toxicity, suitability for intravenous and oral administration, high biodegradability, and good absorption in the human body. 39 In view of our ongoing studies exploiting the plant-mediated strategies for the assembly of nanoparticles, the synthesis of calcium carbonate nanowires and their anti-leishmanicidal effects were undertaken; calcium nanowires were synthesized using a plant extract and then, their anti-leishmanicidal effects were examined on Leishmania major in in vitro.…”
