“…The shift in the position of the peak to 3286 and 3279 cm −1 in the spectrum of the (DREAgNPs) and (DREAgNP-Cu) indicates the binding of Ag + and Cu 2+ ions respectively with amino and hydroxyl groups [28]. The band at 1076 cm −1 is due to the C-N stretch and the shift to 1073 and 1082 cm The synthsized silver nanoparticles show many peaks present in the DRE this due to the phyto chemical compound in the Delonix regia extract as capping and reducing agent of Ag + to Ag 0 and forming AgNPs [34,35] and help in biosorption of Cu 2+ ions.…”

In this research synthesis of silver nanoparticles by a green method is studied. The high importance of silver nanoparticles using extract of Delonix regia (DREAgNs) is due to their unique properties, such as non-expensive, easily available and have application in water treatment. Synthesized silver nanoparticles AgNPs were characterized using UV-Visible Spectrophotometer to indicate the synthesis of AgNPs by green methods. The maximum absorbance of UV-Vis. analysis at wavelength 464 nm. (FT-IR) spectra to indicate the functional groups of phytochemical compounds at Delonix regia extract (DRE) and the silver nanoparticles (DREAgNPs) and also shows the role of active chemical constituents in stabilization and reduction of (DREAgNPs). Based on the transmission electron microscopy image analyses (TEM) confirmed the formation of spherical DREAgNPs with a particle size range of 20-50 nm with an average particle size of 35 nm. The Cu2+ ion adsorption process was studied by (DREAgNPs). The Cu2+ ions removal efficiency (R. E.) is 88.4 % at an initial concentration 15 ppm. Removal efficiency (R. E.) decreases as the Cu2+ ion concentration increases. Furthermore, thermodynamic studies confirmed that the biosorption process was endothermic and the positive value of ΔG° is quite common when an ion-exchange mechanism applies in the biosorption. The Positive value of ΔS◦ suggested an increase in randomness during the biosorption. The Freundlich isotherm has a good fit with the experimental data (R2 =0.99) compared to Langmuir isotherm (R2 = 0.90). This study shows that DREAgNPs are available, low cost, effective and environment friendlly biosorbent for the removal of Cu2+ ions from aqueous environment.

In this study, we used the aqueous extract of garlic tunicate leaf to reduce a mixture of equal amounts of ruthenium chloride, silver nitrate, and palladium acetate for the biosynthesis of ruthenium/silver/palladium trimetallic nanocomposite (Ru/Ag/Pd)-Np. Some physicochemical tools were used for nanocomposite characterization, including Fourier-transform infrared spectroscopy (FT-IR), X-ray di raction (XRD), thermal gravimetric analysis (TGA), UV-Vis spectroscopy (UV-Vis), scanning electron microscope (SEM), and transmittance electron microscope (TEM). XRD revealed that the crystal size of the nanocomposite is 15.67 nm. e TEM images showed that the particle size ranged 50-90 nm. e antimicrobial e cacy of the nanocomposite was examined against Aspergillus avus, Aspergillus niger, Candida albicans, Candida glabrata, Escherichia coli, and Bacillus cereus.e results showed a potent antimicrobial activity toward all tested microorganisms. (Ru/Ag/Pd)-Np showed antiproliferative activity against Caco-2, HepG2, and K562 cell lines. e antiproliferative potential of (Ru/Ag/Pd)-Np was signi cantly improved following UV irradiation.

“…Approximately 20 lakhs of nosocomial infections occur in the United States of America that cost nearly USD 11 billion annually [2]. These infections are extremely difficult to handle because of biofilm-forming bacteria (e.g., MRSA (methicillin-resistant S. aureus) and VRE (vancomycinresistant Enterococcus)), which are highly resistant to conventional antibiotic therapies Materials 2022, 15, 4813 2 of 16 and are very dangerous for patients' health [3,4].

The use of medical devices for therapeutic and diagnostic purpose is globally increasing; however, bacterial colonization on therapeutic devices can occur, causing severe infections in the human body. It has become an issue for public health. It is necessary to develop a nanomaterial based on photothermal treatment to kill toxic bacterial strains. Appropriately, high photothermal conversion and low-cost powerful photothermal agents have been investigated. Recently, gold nanocomposites have attracted great interest in biological applications. Here, we prepared rod-shaped Se-Te@Au nanocomposites of about 200 nm with uniform shape and surface-coated with gold nanoparticles for the first time showing high anti-bacterial and anti-cancer activities. Se-Te@Au showed proper structural consistency and natural resistance to bacterial and cancer cells. The strong absorption and high photothermal conversion efficacy made it a good photothermal agent material for the photothermal treatment of bacterial and cancer cells. The Se-Te@Au rod showed excellent anti-bacterial efficacy against Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus, with highest recorded inhibition zones of 25 ± 2 mm and 22 ± 2 mm, respectively. More than 99% of both types of strains were killed after 5 min with a near-infrared (NIR) laser at the very low concentration of 48 µg/mL. The Se-Te@Au rod’s explosion in HeLa cells was extensively repressed and demonstrated high toxicity at 100 µg/mL for 5 min when subjected to an NIR laser. As a result of its high photothermal characteristics, the exceptional anti-bacterial and anti-cancer effects of the Se-Te@Au rod are considerably better than those of other methods previously published in articles. This study could open a new framework for sterilization applications on the industrial level.
