The peak at 1704 cm -1 corresponds to carbonyl group (=CO) stretching, indicating that the carboxymethyl group (-COOCH3) has been incorporated into the β-CD molecule. With a minor shift, all of the prominent peaks of CM-β-CD in the region of 900-1200 cm -1 are present in the spectrum of CM-β-CD-MNP. two peaks formed at 1623 and 1401 cm -1 , indicating that the COOH groups of CM-β-CD reacted with the surface OH groups of Fe3O4 particles, resulting in the creation of the iron carboxylate. (Figure & S4 in SI). The digital morphology of the compounds was depicted in Figure & S6 in SI. 3.2g. DLS: DLS showed the size range for M MMTs/MNP, MNPs in the range of -228.9 to 3728 d-nm material absorption, material RI and viscosity of 0.00, 1.47 and 1.8872 respectively
