“…Song et al attempted to create PtNPs using the leaf extract of Diopyros kaki. A greater than 90% reduction of Pt ions into nanoparticles was illustrated in approximately 2.5 hours [73]. Song and group suggested that the reduction of the Pt ions was due to the presence of functional groups within the leaf extract such as amines, alcohols, ketones and carboxylic acids; as opposed to an enzyme mediated process.…”

“…Song and group suggested that the reduction of the Pt ions was due to the presence of functional groups within the leaf extract such as amines, alcohols, ketones and carboxylic acids; as opposed to an enzyme mediated process. This was based on the fact that the reaction temperature was 95°C and no protein peaks were found in their FTIR analysis [73].…”

Over the past few decades interest in metallic nanoparticles and their synthesis has greatly increased. This has resulted in the development of numerous ways of producing metallic nanoparticles using chemical and physical methods. However, drawbacks such as the involvement of toxic chemicals and the high-energy requirements of production make it difficult for them to be widely implemented. An alternative way of synthesising metallic nanoparticles is by using living organisms such as bacteria, fungi and plants. This "green" method of biological nanoparticle production is a promising approach that allows synthesis in aqueous conditions, with low energy requirements and low-costs. This review gives an overview of some of these environmentally friendly methods of biological metallic nanoparticle synthesis. It also highlights the potential importance of these methods in assessing nanoparticle risk to both health and the environment.techniques, which are generally low-cost and high-volume. However, the need for toxic solvents and the contamination from chemicals used in nanoparticle production limit their potential use in biomedical applications [15]. Therefore a "green", non-toxic way of synthesising metallic nanoparticles is needed in order to allow them to be used in a wider range of industries. This could potentially be achieved by using biological methods.Many bacteria, fungi and plants have shown the ability to synthesise metallic nanoparticles and all have their own advantages and disadvantages (Table 1) [16][17][18]. Intracellular or extracellular synthesis, growth temperature, synthesis time, ease of extraction and percentage synthesised versus percentage removed from sample ratio, all play an important role in biological nanoparticle production. Finding the right biological method can depend upon a number of variables. Most importantly, the type of metal nanoparticle under investigation is of vital consideration, as in general organisms have developed resistance against a small number of metals, potentially limiting the choice of organism. However synthetic biology; a nascent field of science, is starting to address these issues in order to create more generalised chassis, able to synthesise more than one type of metallic nanoparticle using the same organism [19]."Natural" biogenic metallic nanoparticle synthesis can be split into two categories. The first is bioreduction, in which metal ions are chemically reduced into more stable forms biologically. Many organisms have the ability to utilise dissimilatory metal reduction, in which the reduction of a metal ion is coupled with the oxidation of an enzyme [20]. This results in stable and inert metallic nanoparticles that can then be safely removed from a contaminated sample. The second category is biosorption. This involves the binding of metal ions from Journal of Nanomedicine & Nanotechnology J o u rna l of N a n o m ed icine & N a n o te chnolo g y

Here, Syzygium cumini leaf extract (LE) and seed extract (SE) were explored for the synthesis of gold nanoparticles (GNP). LE and SE as well as their polar (water) fractions showed potential for GNP synthesis. Comparative synthesis kinetics and morphological characterisation studies revealed the synthesis of smaller sized GNP by LE than SE. Only polar (water) fractions showed potential for GNP synthesis, which are smaller in size compared to their respective extracts. SE contained more polyphenols and biochemical constituents than LE and therefore, showed higher synthesis rate and bigger sized GNP. Atomic force microscope and scanning electron microscope analysis indicated that both extracts and their fractions catalysed the synthesis of spherical GNP. The average size of GNP synthesised by LE, leaf water fraction (LWF), SE and seed water fraction (SWF) were 24, 23, 35 and 32 nm, respectively. Fourier transform infrared analysis identified the biomolecules involved in the synthesis and stability of GNP. This study documented the potential of S. cumini for the synthesis of GNP in addition to silver nanoparticles (SNP). However, nature and types of polyphenols involved in GNP synthesis seem to be different from that involved in SNP synthesis. This might be the possible reason for smaller sized GNP that SNP.

Three different methods were employed for the synthesis of biogenic gold nanoparticles using the aqueous extracts of Kedrostis foetidissima. The interaction of gold nanoparticles with the phytoconstituents was investigated by FTIR. The complete reduction of chloroaurate ions to gold nanoparticles was monitored using UV-visible spectroscopy under the different plant extract concentration and conditions. The formation of gold nanoparticles was confirmed using XRD, SEM and TEM analysis. The anisotropic and flower-shaped gold nanoparticles of size below 25 nm was confirmed by TEM analysis. Cucurbitacins, the chief constituents of K. foetidissima probably might have interacted with the chloroaurate ions, facilitating the formation of gold nanoparticles. KFL-mediated AuNPs showed 88 % cell viability against bone cancer cell lines at 200 lg/ml concentration using MTT assay. This may be due to the formation of flower-shaped nature of KFL-mediated AuNPs. The novelty of the work lies in the plantmediated synthesis of biocompatible gold nanoparticles of size less than 25 nm showing 88 % of cell viability against bone cancer cell lines.
