FTIR depicting functional groups of silver nanoparticles vs. thyme extract. FTIR peaks of AgNPs reveals few similar functional groups to that of thyme extract as 2924 cm−1 (C-H stretching), 1620 cm−1 (N-H bending), 1510 cm−1 (N-O stretching), and 1175 cm−1 (C-O bending), which potentially act as surface capping and stabilizing groups.
