FTIR analysis of LIV-AgNPs. Panel (a,c) demonstrate feeble stretching signals of functional groups linked with bio-actives on PLE-alone (red) and LIV-AgNPs (green) in the range of 4000 to 3500 cm−1 and 2000 to 15,000 cm−1, at high magnification, respectively. Whereas, panel (b) represents a comparative FTIR spectra analysis of PLE-alone and LIV-AgNPs at full scan scale at normal magnification.
