“…In another study, Dubey et al (2010) synthesized gold and silver nanoparticles with spherical and triangular shapes, using Tanacetum vulgare (tansy) fruits extract. Finally, Sheny et al (2012) produced hexagonal gold nanoparticles with an essential oil from leaves of Anacardium occidentale. In addition to plants, organisms such as fungi and bacteria have been also used to produce nanoparticles, but plants tend to reduce metal ions faster.…”

Gold (Au0) and silver (Ag0) nanoparticles were synthesized using tannic acid (TA) as both reducing and stabilizer. Nanoparticles formation, stability, and interaction with TA were compared to citrate-coated nanoparticles and monitored by UV-Vis, zeta potential, and transmission electron microscopy. TA coating resulted in a red-shift and broadening of bands compared to citrate-coated nanoparticles (NPs-Cit). AgNPs-TA and AuNPs-TA are negatively charged with mean surface charge of -29.4 mV and -29.6 mV, respectively. TEM images showed polydispersety of AuNPs-TA (6-42 nm) and aggregation of AgNPs-TA (12-71 nm). In vitro assays of Leishmania amazonensis promastigotes showed an increment of antileishmanial activity for AgNPs-TA in relation to AgNPs-Cit, while AuNPs-TA and AuNPs-Cit did not affect the protozoas at tested concentrations. CC50 value for AgNPs-TA suggested that TA attenuates nanosilver toxicity comparatively to its precursor (Ag+). This investigation can contribute to the development of new, green, and fast produced drugs aiming at leishmaniasis treatment.

“…One pollutant, 4-NP, is a carcinogen that must be removed from water and soil in the environment. The reduction reaction of 4-NP to 4-AP has been commonly employed in many studies to evaluate the catalytic activity of AuNPs in the presence of sodium borohydride [8,9,[17][18][19][20].…”

The sustainable synthesis of gold nanoparticles from gold ions was conducted with caffeic acid as a green reducing agent. The formation of gold nanoparticles was confirmed by spectroscopic and microscopic methods. Spherical nanoparticles with an average diameter of 29.99 ± 7.43 nm were observed in highresolution transmission electron microscopy and atomic force microscopy images. The newly prepared gold nanoparticles exhibited catalytic activity toward the reduction of 4-nitrophenol to 4-aminophenol in the presence of sodium borohydride. This system enables the preparation of green catalysts using plant natural products as reducing agents, which fulfills the growing need for sustainability initiatives.

The purpose of the present study is to explore the merits and demerits of various biogenic synthesis route of gold nanoparticles using plant materials and microbes. Literature survey indicated that microbe mediated synthesis route is found to be quite effective buttheavailability and feasibility of microbes, enzyme control conditions is of great challenge for the researchers. Among all the available bio-reductants for the synthesis of gold nanoparticles rhizome of Zinger officinale (ginger) has been found more advantageous in accordance with availability, stability, applicability, reaction time, etc. for the fabrication of gold nanoparticles.
