Biosynthesis of core–shell α-Fe2O3@Au nanotruffles and their biomedical applications

Catalytic, Theoretical, and Biological Investigations of Ternary Metal (II) Complexes Derived from L-Valine-Based Schiff Bases and Heterocyclic Bases

“…A broad peak was observed in the ligand 3300–3500 cm −1 region due to the -OH stretching vibration of the ligand (HL), which was not present in the complexes for which the coordination mode of the deprotonated hydroxyl group with metal ions was confirmed. The C=N- (azomethine) stretching frequency of the ligand showed a strong absorbance peak at 1643 cm −1 ; a shift toward the higher wavelength region (1610–1635 cm −1 ) of the metal(II) complexes revealed that the azomethine nitrogen had coordinated with metal ions ( Table 2 ) [ 21 ]. The bands at (1570–1590 cm −1 ) and (1350–1380 cm −1 ) were attributed to the asymmetric and symmetric vibrational frequencies, respectively, of the carboxyl groups present in the amino acid [ 22 , 23 , 24 , 25 ].…”

“…In vitro antibacterial activity for metal(II) complex 1 ( a – h ) was checked against two Gram-negative bacteria ( Escherichia coli and Klebsiella pneumonia ) and one Gram-positive bacterium ( Staphylococcus aureus ) in different concentration ranges from 5–20 µL/mL using the agar diffusion method [ 21 , 52 , 53 ]. The gradient changes were illustrated as graphs ( Figure 9 a–c), and their data are shown in Table 11 .…”

Biosynthesis of ZnO.Ag2O3 using aqueous extract of Haplophyllum obtusifolium: Characterization and cell toxicity activity against liver carcinoma cells

“…Bimetallic nanoparticles are sometimes favored over monometallic nanoparticles due to; their enhanced optical, catalytic, and biological characteristics [1][2][3][4] The bimetallic nanoparticles are created by joining two distinct metal atoms in a single nanoparticle. By the coexistence of two different metals, the synergistic interaction of metals could exhibit particular qualities, especially in biological efficacy, which depends on the arrangement, composition, percentage of the metal atoms, and preparation method [5][6][7][8].…”

Study of photodegradation performance of Zn‐doped CeO2 nanoparticles for wastewater contaminants remediation under visible light

“…The exciting opportunity of using green plants for the biological production of NPs has become quite popular and attracted the attention of many researchers. In addition, the produced NPs by medicinal plants contain lower risks and can be exerted in industrial and medical fields 24–27 …”

“…In addition, the produced NPs by medicinal plants contain lower risks and can be exerted in industrial and medical fields. [24][25][26][27] According to related researches, the fabricated NPs by plants proved to be faster and more stable than the products of other organisms. Because of their different shapes and sizes, plant NPs can offer certain advantages over the products of other biological methods such as those that implicate the usage of bacteria, algae and yeasts, and fungi.…”
