The presence of representative functional groups and intramolecular interactions amid the drugs and GMO in fabricated nanocubosomes were analyzed by FTIR spectroscopy (Bruker, Karlsruhe, Germany) (Iqbal et al., 2021 ; Khan et al., 2022 (link)). Briefly, a small quantity of Cur, TMZ, CTNCs and blank nanocubosomes freeze-dried powder were directly placed on sample chamber and IR spectrum was measured in the IR range (500–4000 cm−1), with 2 mm sec−1 scanning speed for 120 scans with 4 cm−1 resolution.
