FT-IR analysis:
In laboratories, a large part of the measurements is based on absorbance
reactions. The activity of most cholesterol, triglycerides, enzymes,
lipoproteins, creatinine, urea, sugar and a wide range of analytes with
research and clinical applications, drugs and metabolites can be
measured by spectrophotometry. Investigating the molecular structure,
identifying compounds, comparing structures and finding the maximum
absorption wavelength are other spectrophotometry applications in
research problems [45-47].
The FT-IR spectrum of AgNPs is presented in Figure 5. The bands at 433,
471, and 534 belong to the Ag-O bond. The peaks in the range of 400-600
cm-1 have been reported for silver nanoparticles
[47]. In addition, the peaks for organic compounds at 3217, 2919,
1429 to 1675, and 1009 cm-1, which are belonged to
O-H, C-H, C=C, C=O, and C-O bond, confirm the linkage of R. ribessecondary metabolites such as phenolic and flavonoids compounds to the
surface of nanoparticles [44-47].
