“…Where 'D' is AgNPs crystal size, β is the full-width half maximum (FWHM) of diffraction peaks and θ is Bragg diffraction angle and λ (Venu, 2011). The result of FTIR confirmed the presence of protein in the nanoparticles sample which will bind with protein either by free amine group or by cysteine residues in the protein.…”

Synthesis of nanomaterials holds infinite possibilities as nanotechnology is revolutionizing the field of medicine by its myriad applications. Green synthesis of nanoparticles has become the need of the hour because of its eco-friendly, nontoxic, and economic nature. In this study, leaf extract of Rosa damascena was used as a bioreductant to reduce silver nitrate, leading to synthesis of silver nanoparticles (AgNPs) in a single step, without the use of any additional reducing or capping agents. The synthesized nanoparticles were characterized by the use of UV-visible spectroscopy, fourier transform infrared spectroscopy, dynamic light scattering, transmission electron microscopy, and field emission scanning electron microscopy. Time-dependent synthesis of AgNPs was studied spectrophotometrically. Synthesized AgNPs were found to possess flower-like spherical structure where individual nanoparticles were of 16 nm in diameter, whereas the agglomerated AgNPs were in the range of 60–80 nm. These biologically synthesized AgNPs exhibited significant antibacterial activity against Gram-negative bacterial species but not against Gram-positive ones ( Escherichia coli and Bacillus cereus ). Anti-inflammatory and analgesic activities were studied on a Wistar rat model to gauge the impact of AgNPs for a probable role in these applications. AgNPs tested positive for both these activities, although the potency was less as compared to the standard drugs.

“…La biosíntesis de NPs se observa incluso en células humanas (Anshup et al, 2005;El-Said et al, 2014), y en general en los sistemas bioquímicos derivados de seres vivos, es decir, sistemas que muestren capacidad reductora como por ejemplo los extractos frescos o secos obtenidos de organismos vegetales (Mittal et al 2013;Kumar et al 2013;Huang et al, 2015), la miel (Venu et al, 2011), el vino (Mittal et al, 2014), o hasta el material obtenido de la lisis celular (El-Said et al, 2014). Las NPs obtenidas pueden formar óxidos (Haverkamp y Marshall, 2008) o complejos hidratados (Petit et al, 2015), aunque lo que normalmente It seems then that the synthesis of NPs would be the first defensive responses of plants to stress induced by excess metal ions.…”

“…The biosynthesis NPs is observed even human cells (Anshup et al, 2005;El-Said et al, 2014), and generally in biochemical systems derived from living things, that is, systems that exhibit reducing ability as example fresh or dried extracts obtained from plant organisms (Mittal et al, 2013;Kumar et al, 2013;Huang et al, 2015), honey (Venu et al, 2011), wine (Mittal et al, 2014), or to the material obtained from cell lysis (El-Said et al, 2014). The NPs obtained can form oxides (Haverkamp and Marshall, 2008) or complex hydrated (Petit et al, 2015), but what usually happens is the NPs acquire an organic coating adsorbed on the surface of the NPs, which increases its stability and decreases aggregation (Iravani, 2011); i.e., biological agents develop a double function as reducing agents and as coating.…”

ResumenSe presenta una revisión acerca de la biofabricación de nanopartículas (NPs) de metales usando extractos vegetales, cultivos celulares de órganos o bien plantas vivas. Se describen los dos métodos de biofabricación verde de nanopartículas: el proceso bioquímico con extractos y el proceso biológico que involucra células vivas. Se discute el mecanismo redox de biofabricación de NPs, haciendo énfasis en aquellos puntos que requieren mayor dilucidación con el propósito de estandarizar los procesos para adaptarlos a un sistema industrial de producción. Se describe igualmente lo que se conoce acerca del destino de las NPs biofabricadas en células vivas, remarcando el proceso de movilización extra-e intracelular así como entre diferentes tejidos y órganos de la planta. Se discuten por último los factores que regulan la tasa de biofabricación de nanopartículas en las células y tejidos vivos, dirigiendo la atención hacia aquello que se necesita dominar para obtener biofábricas para la producción de NPs en donde la variabilidad de tamaño, forma y reactividad se ajusten a estándares industriales.Palabras clave: balance redox, bioproducción, bioreducción de metales, síntesis química verde. AbstractA review is presented on the biomanufacturing of nanoparticles (NPs) of metals using plant extracts, cell organ cultures or live plants. The two methods of manufacturing green nanoparticles are described: the biochemical process extracts and biological process involving living cells. The redox mechanism biomanufacturing of NPs is discussed, emphasizing those points that require further clarification in order to standardize processes to adapt to an industrial production system. It also describes what is known about the fate of NPs biomanufacturing in living cells, highlighting the process of extra-and intracellular as well as between different tissues and organs of the plant mobilization. Finally the factors discussed that regulate the rate of biomanufacturing of nanoparticles in living cells and tissues, directing attention to what you need to master to obtain bio-factories for the production of NPs where the variability in size, shape and reactivity fit to industry standards.
