Solventless synthesis and optical properties of Au and Ag nanoparticles using Camellia sinensis extract

Rapid detection of Cr(VI) by AgNPs probe produced by Anacardium occidentale fresh leaf extracts

“…There are several reports has been published for the synthesis of AgNPs by both chemical and biological reduction (Yu 2007;Tan et al 2002;Petit et al 1993;Vorobyova et al 1999;Vilchis-Nestor et al 2008;Shiv Shankar et al 2004;Abu Bakar et al 2007;Vigneshwaran et al 2006;Chandran et al 2006;Shankar et al 2004Shankar et al , 2005Philip 2009;Narayanan and Sakthivel 2011), but still we need a standard strategy for the synthesis of AgNPs with good stability and almost neutral toxicity. In this present study, we attempted to synthesize the NPs with good stability from A. occidentale (locally named as Kolla maram, Tamil Nadu, India) leaf extracts extracted at different temperatures 60, 80 and 100°C, respectively.…”

“…Jose-Yacaman and co-workers (Gardea-Torresdey et al 2002 first reported the formation gold and silver nanoparticles by living plants. Green silver nanoparticles have been synthesized using various natural products, such as green tea (Camellia sinensis) (Vilchis-Nestor et al 2008), neem (Azadirachta indica) leaf broth (Shiv Shankar et al 2004), natural rubber (Abu Bakar et al 2007), starch (Vigneshwaran et al 2006), aloevera plant extract (Chandran et al 2006), lemongrass leaves extract (Shankar et al , 2005 leguminous shrub (Sesbania drummondii) (Sharma et al 2007), mushroom extract (Philip 2009), Coleus amboinicus lour (Narayanan andSakthivel 2011), Medicago sativa (Lukman et al 2011), and Citrus sinensis peel (Kaviya et al 2011) to name few. Shankar et al (2004) and Shiv Shankar et al (2004) reported the metallic silver and gold nanoparticle synthesis by using Neem (Azadirachta indica) leaf broth.…”

Catharanthus roseus: a natural source for the synthesis of silver nanoparticles

“…The above synthetic protocol by plant extract or biomass exemplifies the promising application of the green synthesis of metal nanoparticles. Recent research reported that silver nanoparticles have been synthesized using various natural products like green tea (Camellia sinensis) [14] , neem (Azadirachta indica) leaf broth [15] , natural rubber [16] , Aloe vera plant extract [17] , latex of Jatropha curcas [1] , etc.…”

Green Synthesis: Nanoparticles and Nanofibres Based on Tree Gums for Environmental Applications

“…Plant extracts are regarded as one of the most promising natural reducing agents, such as metabolities (e.g. sugars, alkaloids, polyphenols, phenolic acids terpenoids), and proteins and co-enzymes help to synthesis metal and metal oxide nanoparticles [31][32][33][34][35][36][37]. These NPs can be used in biomedical applications due to their production advantages via a biosynthetic route, which fashions the defined size, morphology and high chemical purity of NPs [38].…”
