“…4 Thus far, more than 200 plants have been screened for their potential to produce inorganic NPs. 5,6 Dovepress Dovepress 8842 azizi et al developed palladium nanoparticles (PdNPs) that had remarkable optical, electronic, and chemical properties. These PdNPs are currently being investigated for use as sensors and catalysts.…”

Among nanoparticles used for medical applications, palladium nanoparticles (PdNPs) are among the least investigated. This study was undertaken to develop PdNPs by green synthesis using white tea (W.tea; Camellia sinensis ) extract to produce the Pd@W.tea NPs. The Pd@W.tea NPs were characterized by UV–vis spectroscopy and X-ray diffractometry, and evaluated with transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The Pd@W.tea NPs were spherical (size 6–18 nm) and contained phenols and flavonoids acquired from the W.tea extract. Pd@W.tea NPs has good 1-diphenyl-2-picrylhydrazyl (DPPH), OH, and NO-scavenging properties as well as antibacterial effects toward Staphylococcus epidermidis and Escherichia coli . MTT assay showed that Pd@W.tea NPs (IC 50 =0.006 μM) were more antiproliferative toward the human leukemia (MOLT-4) cells than the W.tea extract (IC 50 =0.894 μM), doxorubicin (IC 50 =2.133 μM), or cisplatin (IC 50 =0.013 μM), whereas they were relatively innocuous for normal human fibroblast (HDF-a) cells. The anticancer cell effects of Pd@W.tea NPs are mediated through the induction of apoptosis and G2/M cell-cycle arrest.

“…This reaction is carried out in an autoclave at a pressure of 15 psi and at 120°C temperature for 10 min. This method is more efficient and rapid synthesis process compared to previously reported green methods mentioned above (Roopana et al 2012;Sathishkumar et al 2009;Yang et al 2010) for the synthesis of Pd nanoparticles.…”

“…There has also been increasing interest in identifying environmental friendly materials that are multifunctional (Nadagouda and Rajender 2008). Previously PdNPs were prepared through green methods using annona squamosa L peel extract (Roopana et al 2012), banana peel extract (Ahok et al 2010), cinnamom zeylanicum bark (Sathishkumar et al 2009), broth of cinnamom camphora leaf (Yang et al 2010) and gum acacia (Keerthi et al 2011).…”

Green synthesis, characterization and catalytic activity of palladium nanoparticles by xanthan gum

Here, we report the synthesis, characterization and catalytic evaluation of palladium nanoparticles (PdNPs) using xanthan gum, acting as both reducing and stabilizing agent without using any synthetic reagent. The uniqueness of our method lies in its fast synthesis rates using hydrothermal method in autoclave at a pressure of 15 psi and at 120°C temperature by 10 min time. The formation and size of the PdNPs were characterized by UV-visible spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy and transmission electron microscopy. The catalytic activity of PdNPs was evaluated on the reduction of 4-nitrophenol to 4-aminophenol by sodium borohydride using spectrophotometry.

“…This approach provides a facile and convenient entry for producing multiple inorganic NPs, especially metal nanoparticles, such as Ag, Au, Pt and Pd have been synthesized by different methods, including bacteria (Husseiny et al 2007), fungi (Sastry et al 2003) and plants (Sharma et al 2007). Microbemediated synthesis of nanoparticles is not industrially feasible as they require the maintenance of highly aseptic conditions (Sathishkumar et al 2009). …”

Nowadays necessities for the green synthesis of nanoparticles are enlarged because of its neutral toxicity and eco-friendly advantages. In this present study, we have explored the rapid biosynthesis of AgNPs at room temperature by the fresh leaf aqueous extract of Anacardium occidentale. Aqueous extracts were prepared at different temperatures 60, 80 and 100°C. Formation of silver nanoparticles (AgNPs) was confirmed by surface plasmon resonance (SPR) peak observed around 400-420 nm in UV-Visible spectra. Among the extracts prepared, 80°C extract showed good shift in UV-Visible spectrum during Cr(VI) detection and a good linear relationship was found between the absorbance ratio (A 510 /A 400 ) against 100 mM-1 lM concentration of Cr(VI). Cr(VI) was confirmed by the red shift of SPR position from 400 to 510 nm. Detection limit of our prepared probe is 1 lM and this simple technique exhibiting high selectivity to Cr(VI) over other tested heavy metal ions. Finally, efficient 80°C extract synthesized AgNPs were characterized by XRD, SEM and TEM. XRD characterization confirmed its face centered cubic structure and confirmed that the prepared AgNPs are crystalline in nature. TEM and SEM characterization results revealed that the AgNPs are in spherical nature. The size of AgNPs was found to be 40-60 nm.
