“…In addition, the peak at 1380 cm −1 peak is due to the COOgroup in carboxylic acid salt, and the band at 1160 cm −1 is assigned to the special broad peak of the β-(1-4) glucosidic bond in polysaccharide unit. However, the peak at 1062 cm −1 is attributed to the stretching vibration mode of the hydroxyl group, 632-989 cm −1 stretching vibration of C-O-C in glucose [24,28]. The FTIR spectrum of Ch-PDMS MNPs exhibits the same bands of chitosan with new absorption peaks as follows.…”

“…Pode ser usada em liberação controlada de fármacos, ser degradada por enzimas no corpo humano e auxiliar na reconstrução de componentes da matriz extracelular (Rana et al, 2010). É um polissacarídeo formado por b-1,4-anidroglucosamina quanto a N-acetilb-1,4anidroglucosamina (Badawy et al, 2017). Pode ser obtida a partir do processo de desacetilação da quitina encontrada em conchas de crustáceos, paredes de células fúngicas ou cutícula de insetos.…”

“…Pode ser incorporada em substâncias funcionais, tais como minerais, vitaminas, óleos, proteínas e produtos naturais biologicamente ativos (Tang et al, 2013). Contém dois grupos reativos, incluindo amino e hidroxila que facilmente se modifica química e fisicamente (Badawy et al, 2017). A combinação de quitosana com outros biopolímeros, como a gelatina, é uma alternativa eficaz para melhorar a resistência mecânica e propriedades físico-químicas.…”
