N-heterocyclic carbine Gold(I) complexes Thioredoxin reductase Reactive oxygen species Drug-resistant bacteria 1. Introduction Antimicrobial resistance is escalating into a profound threat to global public health due to the lack of effective and safe alternative treatments [1]. Carbapenem antibiotics are ...
Finally, the percentage of hemolysis was calculated through the following equation:(2)Hemolysis(%)=SampleAbs-(K-)Abs(K+)Abs-(K-)Abs×100 2.2.9. AuMSS nanoformulations’ cellular internalization The uptake of AuMSS nanoformulations by HeLa and FibH cells was also evaluated through fluorescence...
As part of the study they are investigating the effect of oxygen addition on the leach kinetics. Orway Mineral Consultants will also be investigating the impact upon the comminution circuit as the proportion of primary ore increases. Following this study they will advise Lefa Mine on measures ...
Moreover, the presence weaker signal for carbon, nitrogen and oxygen atoms are attributed due to the presence of biomolecules of the leaf extract. To gain insight into the nanoscale architecture and exotic shapes of starch free and starch stabilized AuNPs, the synthesized nanomaterials were also cha...
MTT formazan was estimated by recording the optical density at 570 nm wavelength as indicated by the following equation. The experiment was performed in triplicate and repeated thrice.Percentageofcellviability%=(SampleAbsorbance/Controlabsorbance)×100 2.6. Cytotoxicity activity MTT compound was used to ...
The photothermal conversion efficiency (η) was calculated according to the following equation: [40].η%=cmΔTwt×100% Here, c represents the specific heat capacity of Ag@Au nanoplates which was estimated to be 4.2 × 103 J/(kg·K); m stands for the mass of Ag@Au nanoplates ...
These excited-state electrons swiftly move into the AuNPs surface, where they react with oxygen to generate active species, specifically superoxide radicals. These reactions effectively impede the recombination of electron-hole pairs, thereby amplifying the efficiency and endurance of the photocatalyst. ...
0.3. The electrolyte solution was purged for 1 h with argon to remove oxygen. At each potential applied to the Au electrode, 400 spectra with a resolution of 4 cm−1 were measured. To analyse the amide I mode in the protein, the half-wave retardation was set to 1600 cm−1. The ...
The concentration of the produced AuNPs were calculated by a previously reported method using Beer-Lambert equation where the extinction coefficient (ε) is 2.01 × 108 M−1cm−1 [20]. 2.3.1.2. Functionalization of AuNPs by CA. Citrate capped-AuNPs were functionalized with CA ...
Gold is a good conductor of heat and electricity. Heat, moisture, oxygen and most corrosive agents have very little chemical effects on gold, making it well-suited for use in coins and jewelry. Modern industrial uses include dentistry and electronics, where gold has traditionally found use becaus...
