Compatibility involving the Drug and Carrier three.three. Compatibility among the Drug and Carrier Inside the medicated nanomaterials, the drug’s physical state and its compatibility with Inside the medicated nanomaterials, the drug’s physical state and its compatibility with the polymeric carrier are extremely important for functional applications. XRD patterns areare ofthe polymeric carrier are very important for functional applications. XRD patterns usually measured to detect the physical state of theof the elements. Within this study, the XRD patten measured to detect the physical state components. In this study, the XRD patterns of CA, MET, and theirand their core heath nanofibers F1 and F2 are presented6. As a crysterns of CA, MET, core heath nanofibers F1 and F2 are presented in Figure in Figure 6. tallinecrystallinethe raw MET powders have quite a few sharp several sharp peaks in their XRD As a material, material, the raw MET powders have peaks in their XRD patterns. Around the contrary, raw contrary, rawshowpowders show notwo halos, suggesting an amorphous patterns. On the CA powders CA no peaks, except peaks, except two halos, suggesting polymer. Inside the XRD patterns of nanofibers F1 andnanofibers F1 and F2, almost all of the an amorphous polymer. Within the XRD patterns of F2, virtually all the sharp peaks of your raw MET disappear, providing disappear, providing a hint that thethe nanofibers have lost their sharp peaks of your raw MET a hint that the MET loaded in MET loaded within the nanofibers original crystalline state crystalline state and amorphous drug olymer nanocomposite. have lost their original and have formed an have formed an amorphous drug olymernanocomposite. The ATRFTIR spectra of MET, CA, and their core heath nanofibers are shown in Figure 7, in which the molecular formula of CA and FA are also offered. Raw CA powders have characteristic peaks at 1728, 1230, 1232, and 1047 cm1. Raw MET powders have characteristic peaks at 3360, 3274, 1673, 1588, 1381, and 1058 cm1. Even so, in the core heathBiomolecules 2021, 11,pearing. These nanofibers mostly exhibit the peaks in the polymer matrix, with some peaks slightly red shifted to a low wavenumber. These phenomena recommend that the secondary interactions occurred involving the CA and MET molecules. By way of example, the CA molecule has numerous C=O groups inside the OAc groups as proton acceptors, whereas the MET molecules have NH and NH2 to act as proton donors. Therefore, hydrogen bonding 9 of 16 can be conveniently formed amongst them, and determine that CA and MET are hugely compatible, and that the core heath nan.
