The confirmation of synthesized QE‐AgNPs was recorded with UV‐vis spectroscopy (Shimadzu, Lambda UV mini‐1240 instrument) at a wavelength from 200 to 700 nm. The role of functional groups in the biosynthesis of QE‐AgNPs was determined by FTIR spectroscopy (IR Prestige‐21 instrument, Shimadzu Spectrometer, Kyoto, Japan), which was recognized at a resolution of 4 cm−1 and using KBr disk. The crystallinity of QE‐AgNPs was confirmed by the XRD spectrum (model: X'PertPro, Panalytical, Holland), which was operated with a current of 30 mA by Cu K−1 radiation at a voltage of 40 kV. TEM microscopy (Zeiss – EM10C, Germany, at a voltage of 80 kV) was applied for morphological analysis of QE‐AgNPs.
Ir prestige 21 instrument
Manufactured by Shimadzu
Sourced in Japan
The IR Prestige-21 is a Fourier Transform Infrared (FTIR) spectrometer manufactured by Shimadzu. It is a lab equipment instrument designed for infrared spectroscopic analysis. The core function of the IR Prestige-21 is to measure the absorption or transmission of infrared radiation by a sample, which can be used to identify and quantify the chemical composition of the sample.

The materials prepared were characterized by SEM (EVO LS15 OXFORD X-act Scanning Electron Microscope with the aid of an Au-coated powdered sample) to determine their morphologies. Their purities were analyzed by EDX and X-ray fluorescence (XRF, Fisher Instruments) studies. Laser light scattering-based particle size analysis (CILAS Particle Size Analyzer NANO DS) were performed to determine their size distributions. FT-IR (Shimadzu IR-Prestige 21 Instrument) spectroscopic studies were done with the KBr pellet method.

All compounds and chemicals were purchased from Sigma-Aldrich Chemicals (Sigma-Aldrich Corp., St. Louis, MO, USA) or Merck KGaA (Darmstadt, Germany). The melting points of the synthesized compounds were assessed by using a MP90 digital melting point apparatus (Mettler Toledo, Ohio, OH, USA) and were uncorrected. The 1H-NMR spectra and 13C-NMR spectra were recorded by using a Bruker 300 MHz digital FT-NMR spectrometer (Bruker Bioscience, Billerica, MA, USA) and collected in DMSO-d6 (Supplementary Materials ). The IR spectra were obtained by using a Shimadzu IR Prestige-21 instrument (Shimadzu, Kyoto, Japan). The LC-MS/MS studies were conducted by using a Shimadzu 8040 LC-MS/MS system (Shimadzu, Kyoto, Japan). The purities of the compounds were checked by TLC on silica gel 60 F254 (Merck KGaA, Darmstadt, Germany). The general synthesis method is presented in Scheme 1 .

C, H and N analyses were carried out with a Thermo Scientific Flash 2000 elemental analyzer. Analytical determination of Na was performed by FAAS on a Perkin Elmer AAnalyst 200 with a 10-cm burner and operated at 589 nm. The hollow cathode lamp (Photron) was operated under the manufacturer's recommendations. The composition of the flame was acetylene (2.5 L/min)-air (10.0 L/min). UV-Vis spectra were recorded in a Shimadzu 1603 spectrophotometer. The FTIR absorption spectra (4000-400 cm -1 ) of the complexes and free ligands were measured as KBr pellets with a Shimadzu IR Prestige-21 instrument. Thermogravimetric measurements (TGA) were done on a Shimadzu TGA 50 thermobalance, with a platinum cell, working under flowing nitrogen (50 mL min -1 ) and at a heating rate of 0.5 °C min -1 (room temperature to 80 °C range) and 1.0 °C min -1 (80-350 °C range). 1 H-NMR spectra were recorded with a Bruker Avance 400 MHz spectrometer in D 2 O at 27 °C. The peak for residual solvent (H 2 O, 4.79 ppm) was used as reference [34] . 31 P-NMR spectra were obtained with the same spectrometer at 161,976 MHz and referred to H 3 PO 4 85% (0.00 ppm).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
