“…In contrast, when the AgNO 3 solution was scanned alone, no distinguishing peak was seen ( Figure 1 b). There have been numerous publications describing the creation of silver nanoparticles by means of green biogenic processes, and the Bougainvillea plant was also used for the synthesis of biogenic nanomaterials ( Table 1 ) [ 31 , 35 , 36 , 37 , 38 , 39 ]. The floral extracts from the Bougainvillaea glabra Miami hot pink flower are still unexplored in terms of anticancer potential, including the antioxidant property and antibiofilm activity.…”

“…Freshly synthesized BAgNPs have been investigated for their antibacterial activity against E. coli and S. aureus strains, which are important human pathogens. Additionally, several methods were used to evaluate the antibacterial activity of the produced silver nanoparticles in previous studies [ 39 , 42 , 44 ]. This study identified silver nanoparticles with the lowest MIC values against MRSA bacterial strains.…”

In this research, Bougainvillea glabra paper flower extract was used to quickly synthesize biogenic silver nanoparticles (BAgNPs) utilizing green chemistry. Using the flower extract as a biological reducing agent, silver nanoparticles were generated by the conversion of Ag+ cations to Ag0 ions. Data patterns obtained from physical techniques for characterizing BAgNPs, employing UV-visible, scattering electron microscope (SEM), transmission electron microscope (TEM), dynamic light scattering (DLS), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR), suggested that the nanoparticles have a spherical to oval form with size ranging from 10 to 50 nm. Spectroscopy and microscopic analysis were used to learn more about the antibacterial properties of the biologically produced BAgNPs from Bougainvillea glabra. Further, the potential mechanism of action of nanoparticles was investigated by studying their interactions in vitro with several bacterial strains and mammalian cancer cell systems. Finally, we can conclude that BAgNPs can be functionalized to dramatically inhibit bacterial growth and the growth of cancer cells in culture conditions, suggesting that biologically produced nanomaterials will provide new opportunities for a wide range of biomedical applications in the near future.

“…As an important noble metal nanocluster, silver clusters have been widely researched due to their unique physical and chemical properties. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] To further improve the electronic properties of silver clusters, more and more studies have been conducted on doped clusters. For example, the central doping of a foreign atom into Ag 25 cluster has a powerful influence on the catalytic performance in the carboxylation reaction of CO 2 with terminal alkyne through C C bond formation to produce propiolic acid.…”

Growth pattern and electronic and magnetic properties of AgnCr (n = 1–16) clusters have been investigated via density functional theory (DFT) combined with CALYPSO structure search method. The optimized geometry shows that the growth of the global minimum structures of AgnCr clusters have obvious rule. when n > 12, silver atoms grow around an icosahedron which is almost unchanged in each structure. Analyses of electronic properties indicate that the doped Cr atom can only enhance the stability of larger silver clusters. Optical absorption and photoelectron spectra of AgnCr isomers have been predicted and can be used for their structural identification. The icosahedral Ag12Cr cluster with large energy level gap can be seen as a superatom. The adsorption capacity of Cr atom in AgnCr cluster to CO is much higher than that of free Cr atom. The intensity of IR and Ramam spectra can be dramatically enhanced when CO is absorbed on AgnCr cluster that Cr atom is encapsulated by Ag atoms. Moreover, the red shift of IR and Raman spectra of CO adsorbed on these clusters is also very small compared to free CO. Magnetism calculations show that the magnetic moment of AgnCr clusters decreases linearly from n = 6 to 12 and increases linearly from n = 12 to 16. The total magnetic moment of AgnCr cluster is mainly localized on the Cr atom. The change of magnetic moment of Cr atom is related to the charge transfer between Cr and Ag atoms.

“…Within the diversity of nanomaterials, metallic nanoparticles (MNPs) have been recurrently studied for a range of applications based on their physicochemical and biological properties, which differ from their analogue in bulk and are strongly influenced by their metallic nature (gold, silver, and copper, among others), due to their size and morphology. Catalytic, sensing, , cancer treatment, antimicrobial, fertilizer, and wastewater remediation applications , have been reported for MNPs. To synthesize MNPs, physical, chemical, or biological methods are used; here, there are two techniques to synthesize nanoparticles: microorganism-mediated synthesis and plant-mediated synthesis .…”

Gold nanoparticles (AuNPs) were synthesized and stabilized using ecological strategies: the extracts of the leaves of the plants Gliricidia sepium (GS) and Petiveria alliacea (PA) reduced the metallic Au ions to AuNPs. The AuNPs were analyzed as surface-enhanced Raman scattering (SERS) substrates for pyridoxine detection (vitamin B6). UV–vis spectroscopy was carried out to assess the stability of the AuNPs. As a result, absorption bands around 530 and 540 nm were obtained for AuNPs-PA and AuNPs-GS, respectively. Both cases associated it with localized surface plasmon resonance (LSPR). In the final stage of the synthesis, to stabilize the AuNPs, carboxymethyl cellulose (CMC) was added; however, LSPR bands do not exhibit bathochromic or hypsochromic shifts with the addition of CMC. Transmission electron microscopy (TEM) micrographs show relatively spherical morphologies; the particle diameters were detected around 7.7 and 12.7 nm for AuNPs-PA and AuNPs-GS, respectively. The nanomaterials were evaluated as SERS substrates on pyridoxine, revealing an intensification in the vibrational mode centered at 688 cm –1 associated with the pyridinic ring. Complementarily, different density functional theory functionals were included to obtain molecular descriptors on the Au n -cluster-pyridoxine interaction to study the SERS behavior.
