“…Pd NPs are biosynthesized using various plant species, and the sizes, shapes, monodispersity, yield, and crystallinity of the fabricated nanoparticles are controlled by optimizing the synthesis conditions ( Figure 2 and Table 1 ) [ 61 , 62 ]. The prepared Pd NPs were characterized using UV/Vis spectrophotometry, dynamic light scattering (DLS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and powder X-ray diffraction (XRD).…”

“…The prepared Pd NPs were characterized using UV/Vis spectrophotometry, dynamic light scattering (DLS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and powder X-ray diffraction (XRD). Spectroscopic and diffractographic techniques play a crucial role in the identification and characterization of Pd NPs [61,62]. Phytosynthesis of spherical Pd NPs with an average size of 21.55 nm was performed using Solanum nigrum leaf extract [25].…”

Palladium nanoparticles (Pd NPs) showed great potential in biomedical applications because of their unique physicochemical properties. Various conventional physical and chemical methods have been used for the synthesis of Pd NPs. However, these methods include the use of hazardous reagents and reaction conditions, which may be toxic to health and to the environment. Thus, eco-friendly, rapid, and economic approaches for the synthesis of Pd NPs have been developed. Bacteria, fungi, yeast, seaweeds, plants, and plant extracts were used to prepare Pd NPs. This review highlights the most recent studies for the biosynthesis of Pd NPs, factors controlling their synthesis, and their potential biomedical applications.

“…The average sizes, morphologies, and crystallinity of the synthesized nanoparticles are optimized via controlling the reaction conditions, including pH, temperature, and contact time [51,52]. In addition, different analytical tools were utilized to characterize the fabricated MNPs in general and PtNPs in specific, including UV/Vis spectrophotometry, dynamic light scattering (DLS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and powder X-ray diffraction (XRD) [53][54][55][56][57][58][59][60].…”

Platinum nanoparticles (PtNPs) have superior physicochemical properties and great potential in biomedical applications. Eco-friendly and economic approaches for the synthesis of PtNPs have been developed to overcome the shortcomings of the traditional physical and chemical methods. Various biogenic entities have been utilized in the green synthesis of PtNPs, including mainly plant extracts, algae, fungi bacteria, and their biomedical effects were assessed. Other biological derivatives have been used in the synthesis of PtNPs such as egg yolk, sheep milk, honey, and bovine serum albumin protein. The green approaches for the synthesis of PtNPs have reduced the reaction time, the energy required, and offered ambient conditions of fabrication. This review highlights the state-of-the-art methods used for green synthesis of PtNPs, synthesis parameters, and their reported biomedical applications.

“…The selective medium of selenium-tolerant bacteria was prepared using nutrient agar media enriched with 10, 20, 30, 40, 50, and 100 μg/ml of Sodium selenite, as described by Shahverdi et al [20]. A sodium selenite stock solution (2.19 g/l corresponding to 1 g/l of Se) was prepared and sterilized by filtration (single use syringe filter, 0.20 mm, Sartorius Stedim Biotech).…”

In the present study, the isolation of selenium (Se)-enriched bacteria from rumen fluid and hot spring water was carried out. Rumen fluid samples were taken from cannulated goats fed a basal diet and the water samples were collected from Selayang hot spring, Selangor-Malaysia. A total number of 140 Se-tolerant isolates were obtained aerobically using an Se-enriched medium and spread plate technique. All the isolates were initially screened for the ability to transform the Se-containing medium to a red-orange culture using a spectrophotometer. Twenty isolates of dark red-orange medium were selected for a screening of the highest Se-containing protein accumulating strains using the dialysis technique and icp.ms to measure the Se content. Four isolates, identified as Enterobacter cloacae (ADS1, ADS7, and ADS11), and Klebsiella pneumoniae (ADS2) from rumen fluid origin, as well as, one isolate from hot spring water (Stenotrophomonas maltophilia (ADS18)), were associated with the highest biomass organic Se-containing protein when grown in a medium enriched with 10 µg/ml sodium selenite. In addition, around 50 µg/100 µg of the absorbed inorganic Se was accumulated as an organic form. Organic Se-containing protein in all the selected strains showed antioxidant properties in the range of 0.306 to 0.353 Trolox equivalent antioxidant capacity (TEAC) mg/ml. Therefore, these strains may offer a potential source of organic Se due to their Se-tolerant nature and higher biomass organic to inorganic Se ratio.
