Samples but with a decreasedInt. J. Mol. Sci. 2021, 22, x FOR PEER REVIEW4 ofInt. J. Mol. Sci. 2021, 22,Fourier-transform infrared (FTIR) spectroscopy analyses showed structural alterations 4 of 9 in NA and amelotin upon self-assembly and HAP formation (Figure 2b). Hydroxyl groups have been recorded as broad peaks at 3410 cm-1 in all protein samples but using a decreased intensity, presumably because of close association with HAP. Furthermore, the peak correspondintensity, presumably bending mode [24] appeared at around peak corresponding ing to PO43- groups in because of close association with HAP. In addition, the1140 cm-1. Here, the to PO4 3- groups in bending mode [24] appeared at around 1140 cm-1 . Right here, the latter value is considerably shifted compared to the synthetic HAP sample. These results latter that when self-assembled amelotin is always to the synthetic NA sample. These results show worth is considerably shifted compared incubated with HAPnanoribbons, the two show that when self-assembled amelotin is incubated with NA proteins interact inside a manner that promotes HAP mineralization.nanoribbons, the two proteins interact inside a manner that promotes HAP mineralization. Further mineralization experiments have been performed to evaluate the ability of amelotin Further mineralization experiments had been performed to evaluate the capacity of amelotin to market HAP formation in the presence of NA scaffolds for guided mineral to promote HAP was assembled presence of NA in CaP for guided mineral development. development.
