“…Various nanostructured materials have been prepared using the green synthesis of metal nanoparticles (MNPs) using plant-based materials and substances [17][18][19][20]. These green-synthesized MNPs possess unique, self-assembling properties, greater surface to volume ratio, a size-dependent crystalline structure (1-100 nm), higher stability, specificity, encapsulation, surface structure, and biocompatibility due to their material structure MNPs/organic capping [21] when compared to chemically synthetized MNPs.…”

Among the MNPs, AuNPs possess interesting optical and electronic properties, which give them high chemical stability and surface area, and which mean they could be used in bio-medic, catalytic, photonics, and sensing applications [19,22,23].…”

Detection and quantification of diverse analytes such as molecules, cells receptor and even particles and nanoparticles, play an important role in biomedical research, particularly in electrochemical sensing platform technologies. In this study, gold nanoparticles (AuNPs) prepared by green synthesis from Sargassum sp. were characterized using ultraviolet-visible (UV-Vis) and Fourier transform-infrared (FT-IR) spectroscopies, X-ray diffraction (XRD), scanning electron microscopy (SEM), dynamic light scattering (DLS) and zeta potential (ζ) obtaining organic capped face-centered cubic 80–100 nm AuNPs with an excellent stability in a wide range of pH. The AuNPs were used to modify a carbon nanotubes-screen printed electrode (CNT-SPE), through the drop-casting method, to assemble a novel portable electrochemical sensing platform for glucose, using a novel combination of components, which together have not been employed. The ability to sense and measure glucose was demonstrated, and its electrochemical fundamentals was studied using cyclic voltammetry (CV). The limits of detection (LOD) and quantification (LOQ) to glucose were 50 μM and 98 μM, respectively, and these were compared to those of other sensing platforms.

“…Despite various other methods of synthesizing nanoparticles, the eco-benign approach has been the most sought after. Besides, microbial synthesis, plant product/phytochemicalmediated synthesis of nanoparticles has drawn much attention because of its availability, reproducibility, and reliability [10][11][12][13][14][15][16][17]. This study reports on the eco-friendly green syntheses of silver nanoparticles (Ag NPs) using two plant extracts such as Alternanthera sessilis leaf and Oregano root extracts as a reduction agent.…”

Silver nanoparticles (Ag NPs) were synthesized using Alternanthera sessilis leaf and Oregano root extract in an eco-friendly fashion and their significant physicochemical and optochemical properties were ascertained for nano-defined characteristics. The UV-visible spectrum showed a single and distinct absorbance peak at 433 nm (Alternanthera sessilis) and 425 nm (Oregano), typical SPR (surface plasmon resonance) for silver. Structural studies revealed nano-crystal with face centre cubic (FCC) symmetry with monodispersed nature. SEM studies showed spherical-shaped particles and the purity determined from EDX spectrum. The synthesized Ag NPs showed that antibacterial activity was studied. There was a significant inhibitory effect toward clinically important pathogens viz. B. subtilis, S. aureus, P. aeruginosa, and E. coli exposed to Ag NPs at different concentrations.

“…To determine the stability and dispersion of the AuNPs, Z potential was measured (DLS, Litesizer 500, Anton Paar, Austria). A total of 100 µL of AuNPs was dispersed in 1 mL of water at different pHs (4, 7.4, and 11) with n = 3 [ 45 ]. AuNPs’ morphology and size were determined by scanning electron microscopy (SEM) and scanning transmission electron microscopy (STEM) analysis using an SEM/STEM Hitachi microscope (Hitachi High-Tec Tokio, Japan).…”

In this study, green chemistry was used as a tool to obtain gold nanoparticles using Amphipterygium adstringens extracts as a synthesis medium. Green ethanolic and aqueous extracts were obtained using ultrasound and shock wave-assisted extraction. Gold nanoparticles with sizes ranging between 100 and 150 nm were obtained with ultrasound aqueous extract. Interestingly, homogeneous quasi-spherical gold nanoparticles with sizes between 50 and 100 nm were achieved with shock wave aqueous-ethanolic extracts. Furthermore, 10 nm gold nanoparticles were obtained by the traditional methanolic macerate extraction method. The physicochemical characteristics, morphology, size, stability, and Z potential of the nanoparticles were determined using microscopic and spectroscopic techniques. The viability assay in leukemia cells (Jurkat) was performed using two different sets of gold nanoparticles, with final IC50 values of 87 µM and 94.7 µM, reaching a maximum cell viability decrease of 80% The results do not indicate a significant difference between the cytotoxic effects produced by the gold nanoparticles synthesized in this study and vincristine on normal lymphoblasts (CRL-1991).
