Aim:
The aim was to investigate the interaction of the biosynthesized silver nanoparticles (AgNPs) with poly (methyl methacrylate) (PMMA) denture base resin using Fourier transform infrared (FTIR) spectroscopy.
Settings And Design:
This was a comparative in vitro study.
Materials And Methods:
In the present study, AgNPs were biosynthesized using Trigonella foenum-graecum leaf extract. The biosynthesized AgNPs at concentrations 32 and 64 μg/ml were incorporated into PMMA, and characterization was carried out using FTIR spectroscopy.
Statistical Analysis Used:
None, as only one sample from each group was subjected for FTIR spectroscopy.
Results:
The biosynthesis of AgNPs was confirmed by a color change from green to brown. When compared to the control group, the test group showed no changes in the band locations for C = C and C = O. Importantly, the infrared spectra of all specimens with AgNP additives exhibited the distinctive peaks associated with PMMA.
Conclusion:
Based on the study's limitations, it was determined that AgNPs had physically interacted with the PMMA matrix.
