Nanotechnology is the formation, running and use of operation at the nanomaterial size scale (1–100 nm). Nanoscale materials can also be obtained by biological synthesis materials via eco-friendly green chemistry based technique. Current development and numerous strategies involved in the green synthesis of nanoparticles were focussed. This review mainly focused on plants which include scientific name, family name, common name, plant parts, its characterization, size and shape of the nanoparticles. Plant extract which was done experimentally gives its various characterization which leads to the identification of compounds of different nano size and shape. Biosynthesis of gold nanoparticles is in different shapes like spherical, rod, cubic, triangle and also in different sizes. Various application and importance of gold nanoparticles in numerous fields were discussed. The mark of the review is to provide an overview of recent learning in biosynthesized nanoparticles, its characterization and their potential applications.

“…However, inhibitory effects of higher concentrations of Au 3+ on root growth of alfalfa and other growth attributes reduction in various plants species have also been reported [ 5 , 23 , 24 ]. In general, metallic gold with zero nutritive value does not cause toxicity but higher concentrations of gold solutions may cause toxicity, affect plant growth adversely [ 2 , 18 , 23 , 24 ] and may produce changes at physiological, biochemical and molecular levels [ 2 , 8 , 25 – 27 ].…”

“…Formation of monodispersed spherical gold nanoparticles in roots of Arabidopsis grown hydroponically in the presence of 10 ppm of KAuCl 4 was observed [ 26 ]. Its yield was also found to be plant organ dependent, for example, shoot extract of Cucurbita pepo produced large number of spherical nanoparticles of smaller size than those produced from roots [ 27 ]. In order to understand the formation of metal nanoparticles in plants, Brassica juncea was hydroponically grown in the presence of AgNO 3 and HAuCl 4 separately [ 50 ].…”

Engineered Gold Nanoparticles and Plant Adaptation Potential

Use of metal nanoparticles in biological system has recently been recognised although little is known about their possible effects on plant growth and development. Nanoparticles accumulation, translocation, growth response and stress modulation in plant system is not well understood. Plants exposed to gold and gold nanoparticles have been demonstrated to exhibit both positive and negative effects. Their growth and yield vary from species to species. Cytoxicity of engineered gold nanoparticles depends on the concentration, particle size and shape. They exhibit increase in vegetative growth and yield of fruit/seed at lower concentration and decrease them at higher concentration. Studies have shown that the gold nanoparticles exposure has improved free radical scavenging potential and antioxidant enzymatic activities and alter micro RNAs expression that regulate different morphological, physiological and metabolic processes in plants. These modulations lead to improved plant growth and yields. Prior to the use of gold nanoparticles, it has been suggested that its cost may be calculated to see if it is economically feasible.

“…Seed mediated biosynthesis: Application of seed has been studied for the biosynthesis of gold nanoparticles. Seeds of Vitis vinifera [141], Cajjanus cajau [142], Cucurbita pepo [143], Ocimum sanctum [144] have been studied to carry out biosynthesis process. Gold nanoparticles prepared by using seed extract of plant Elettaria cardamomum has been studied for its antifungal and antibacterial activities [145].…”

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.
