Plants: Emerging as Nanofactories towards Facile Route in Synthesis of Nanoparticles

Assessment of three plant extracts to obtain silver nanoparticles as alternative additives to control biodeterioration of coatings

“…In addition to this, Shankar et al observed that comparing the use of Pelargonium graveolens extract with earlier studies, using bacteria or fungi, the reduction of the same ions was faster, completing more than the 90% within 9 h, whereas using microorganisms were ranged from 24 to 124 h (Shankar et al, 2003). Reports also suggest that specific components founded in different plant species could be relevant to NPs synthesis; an example is an emodin, a resin with quinone compounds, which is present in xerophytes plants which are adapted to environments with little water (Baker et al, 2013;Singh et al, 2016b).…”

“…These methods use cells as nanofactories or the extracts obtained from them (Mittal et al, 2013). Several bacteria, fungi, plants and marine algae have been reported for the last two decades to the biogenic nanoparticle synthesis (Baker et al, 2013;Durán et al, 2007;Elbeshehy et al, 2015;Singh et al, 2015). Plant extracts could be advantageous over other environmentally benign processes due to they eliminate the cost of maintaining cell cultures and also are suitably for large-scale synthesis (Kumar and Yadav, 2009).…”

Noble Metal Nanoparticles: Plant-Mediated Synthesis, Mechanistic Aspects of Synthesis, and Applications

“…Nanoparticles exhibit a wide range of improved and new physicochemical properties that are significantly different from their bulk counterparts. The material particles generally show interesting and even surprising properties when they are in the nanorange of 1–100 nm . This is because, as the size of the particles approaches nanoscale, the percentage of atoms present at the surface of a material becomes significant and the larger surface area of nanoparticles dominates the contribution made by a small bulk of material .…”

Medical Uses of Silver: History, Myths, and Scientific Evidence

“…There are four factors influencing the synthesis of AgNPs based on plant extracts which also affect the particles size: − pH. A variation in pH alters the charges of the biomolecules in the extracts which can interact in different ways with the Ag + cation, thus determining the properties of the AgNPs produced. Temperature.…”
