“…The high stability of AgNPs plays an important role for their application in biomedical and diagnostic fields [2]. Similar results were obtained with the AgNPs synthesized from leaf extract of Convolvulus arvensis that had negative surface zeta potential value pointing towards their high stability and large surface area [26].…”

Biological synthesis of silver nanoparticles using plants is gaining importance as an economically viable and ecofriendly approach. The present study reports synthesis of silver nanoparticles using an important Himalayan medicinal herbal plant Ocimum kilimandscharicum and the potential of biosynthesized silver nanoparticles for control of plant pathogens. The reducing effect of the aqueous plant extract for synthesis of silver nanoparticles was investigated at different concentrations and temperatures. UV-visible absorption spectrum recorded for samples prepared with different concentrations (20, 30, 40 and 50% v/v) of plant extract and treated at different temperatures (40, 60, 80 °C and room temperature) confirmed the formation of silver nanoparticles. Antimicrobial activity of the silver nanoparticles was tested against Fusarium oxysporum, Colletotrichum gloeosporioides, Bacillus sp. and Enterobacter cloacae. Complete inhibition of F. oxysporum was observed at 75 ppm concentration of silver nanoparticles as compared to 67.75 ± 1.15 mm radial growth without silver nanoparticles after 7 days of incubation. No growth of C. gloeosporioides was observed in vitro at 100 ppm silver nanoparticles as compared to 44.50 ± 1.14 mm radial growth in the absence of the silver nanoparticles. Inhibitory effect of biosynthesized silver nanoparticles was also observed against bacterial pathogens. The highest inhibition zone of 14.5 ± 1.11 mm was observed against E. cloacae with 100 ppm silver nanoparticles. The obtained results confirm strong antimicrobial activity of the silver nanoparticles synthesized using O. kilimandscharicum against plant pathogens.

“…An octahydrazide derivative of resorcinarene RA-5 was successfully used to reduce silver nitrate [108]. Obtained luminescent nanoparticles (d = 7 ± 1 nm) showed pronounced antibacterial activity and were stable in wide range of temperatures (10-50 • C) and pH (4)(5)(6)(7)(8)(9)(10). Dispersions were stable at room temperature for 120 days.…”

Silver nanoparticles (AgNPs) are an attractive alternative to plasmonic gold nanoparticles. The relative cheapness and redox stability determine the growing interest of researchers in obtaining selective plasmonic and electrochemical (bio)sensors based on silver nanoparticles. The controlled synthesis of metal nanoparticles of a defined morphology is a nontrivial task, important for such fields as biochemistry, catalysis, biosensors and microelectronics. Cyclophanes are well known for their great receptor properties and are of particular interest in the creation of metal nanoparticles due to a variety of cyclophane 3D structures and unique redox abilities. Silver ion-based supramolecular assemblies are attractive due to the possibility of reduction by “soft” reducing agents as well as being accessible precursors for silver nanoparticles of predefined morphology, which are promising for implementation in plasmonic sensors. For this purpose, the chemistry of cyclophanes offers a whole arsenal of approaches: exocyclic ion coordination, association, stabilization of the growth centers of metal nanoparticles, as well as in reduction of silver ions. Thus, this review presents the recent advances in the synthesis and stabilization of Ag (0) nanoparticles based on self-assembly of associates with Ag (I) ions with the participation of bulk platforms of cyclophanes (resorcin[4]arenes, (thia)calix[n]arenes, pillar[n]arenes).
