Ir solution software v1

FTIR spectra of ALEX-M, ALEX-M-PNCs and B-PNCs were recorded on FTIR spectrometer (Nexus 670 Fourier Transform Infrared). The actual spectra of the nanocapsules were measured from 400 to 4000 cm⁻¹ having a resolution of 4 cm⁻¹. The measurements were adjusted toward deionized water as the background solvent. Baseline manipulation and data acquisition were gained using Shimadzu IR solution software v1.40. The method used followed the method adopted by Nur and Vasiljevic (2018 ).

FTIR spectra of the particles at different pH (3.7, 4.3, 4.6, 6) and concentrations of tragacanth (0.1%, 0.5%, and 1%) were acquired by using a Perkin Elmer ATR-FTIR spectrometer equipped with a Diamond TM ZnSe single reflection ATR plate (Perkin-Elmer, Norwalk, CT, USA). The actual spectrum of every sample was acquired from 16 scans from 600 to 4000 cm⁻¹ having a resolution of 4 cm⁻¹ as well as strong apodisation. This particular measurement was adjusted towards the background spectrum of the solvent. Baseline manipulation and data acquisition were gained using Shimadzu IR solution software v1.40 [18 (link),22 (link)].
