“…The reaction was continued for the next 5 h. After that time, it was observed that as the incubation time increased, the intensity of the absorption peak at 265 nm significantly lowered. Finally, it disappeared and was replaced by a broad continuous absorption spectrum between 200 and 300 nm, which indicated the formation of platinum nanoparticles (Leo and Oluwafemi 2017). During mixing, a change of color was observed: from yellow to yellowish brown.…”

Due to the search for new methods for synthesizing nanomaterials, this work proposes the biological synthesis of platinum nanoparticles using Ononidis radix extract. The synthesized platinum nanoparticles were characterized by UV-Vis, Scanning Electron Microscopy (SEM) with EDS profile, Fourier transform infrared spectroscopy (FTIR), Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM). The examination conducted by means of Transmission Electron Microscopy showed the presence of spherical and hexagonal platinum nanoparticles. Atomic Force Microscopy indicated the presence of locally agglomerated nanoparticles whose size was about 4 nm. The study also examined the influence of platinum nanoparticles on human non-small cell lung carcinoma cells A549. It was found that the mortality of cells cultured together with platinum nanoparticles increased, and the proliferative activity of A549 cells decreased gradually over time in proportion to the increasing concentration of the test substance.

“…After mixing plant extracts and H 2 PtCl 6 , the color of the reaction mixture gradually changed from pale yellow to brown or black, indicating the reduction to Pt 0 [79][80][81][82][83]. The green-mediated PtNPs exhibited surface plasmon resonance around 230 to 295 nm and a cubic structure XRD pattern of ( 111), ( 200), (220), and (311) [81,82] with a zeta potential of −17.28 to −0.0536 mV [80,84,85]. PtNPs have shown promising antimicrobial activity against pathogenic bacteria [79,80,82], as well as antioxidant capacity [80][81][82].…”

The synthesis of inorganic nanoparticles for diverse applications is an active research area that involves physical and chemical methods, which typically are expensive, involve hazardous chemical reagents, use complex equipment and synthesis conditions, and consume large amounts of time and energy. Thus, green synthesis methods have emerged as eco-friendly and easy alternatives for inorganic nanoparticle synthesis, particularly the use of plant-based extracts from fruit juice, leaves, seeds, peel, stem, barks, and roots, which act as reducing, capping, and stabilizing agents, contributing to the Sustainable Development Goals and circular economy principles. Therefore, diverse inorganic nanoparticles have been synthesized using plant-based extracts, including gold, silver, titanium dioxide, zinc, copper, platinum, zirconium, iron, selenium, magnesium, nickel, sulfur, cobalt, palladium, and indium nanoparticles, which exhibit different biological activities such as antioxidant, antimicrobial, dye degradation, cytotoxic, analgesic, sedative, wound-healing, skin protection, sensor development, and plant-growth-promoting effects. Therefore, this review summarizes the advantages and limitations of plant-based extracts as reducing, capping, and stabilizing agents for inorganic nanoparticle green synthesis.

“…Both NPs were exploited in antibacterial and biomedical applications [ 32 ]. Few studies revealed that Pt NPs can be biosynthesized from cyanobacteria [ 33 ], seaweeds [ 34 ], tea extracts [ 35 ], honey [ 36 ], and eggs [ 37 ]. Platinum salts such as H 2 PtCl 6 , K 2 PtCl 6 , K 2 PtCl 4 , PtCl 2 , Pt(AcAc) 2 , Pt(NH 3 ) 4 (OH) 2 , Pt(NH 3 ) 4 (NO 3 ) 2 , and Pt(NH 3 ) 4 Cl 2 are applied for biosynthesis [ 38 ].…”

The ambition to combat the issues affecting the environment and human health triggers the development of biosynthesis that incorporates the production of natural compounds by living organisms via eco-friendly nano assembly. Biosynthesized nanoparticles (NPs) have various pharmaceutical applications, such as tumoricidal, anti-inflammatory, antimicrobials, antiviral, etc. When combined, bio-nanotechnology and drug delivery give rise to the development of various pharmaceutics with site-specific biomedical applications. In this review, we have attempted to summarize in brief the types of renewable biological systems used for the biosynthesis of metallic and metal oxide NPs and the vital contribution of biogenic NPs as pharmaceutics and drug carriers simultaneously. The biosystem used for nano assembly further affects the morphology, size, shape, and structure of the produced nanomaterial. The toxicity of the biogenic NPs, because of their pharmacokinetic behavior in vitro and in vivo, is also discussed, together with some recent achievements towards enhanced biocompatibility, bioavailability, and reduced side effects. Because of the large biodiversity, the potential biomedical application of metal NPs produced via natural extracts in biogenic nanomedicine is yet to be explored.
