Aplicações do quitosano como biomaterial
2016Os biomateriais podem ser utilizados para substituir, no todo ou em parte, sistemas biológicos quando estes são impossibilitados de cumprir as suas funções naturais. Atualmente existe uma panóplia de biomateriais que podem ser divididos, de acordo com a sua origem, em materiais naturais e sintéticos.

Despolimerización de quitosano con peryodato de potasio
2011La degradación de quitosano con peryodato de potasio fue estudiada en condiciones acuosas bien controladas (tampón de ácido acético (0,3M)/acetato de sodio (0,2M) y 25ºC) con el fin de establecer cual es el proceso preferencial que ocurre durante los estadios iniciales de la reacción.

Citocompatibilidade de matrizes de quitosano/fosfato de cálcio
2014The design of appropriate structures to restore or to improve tissue function is a major challenge in tissue engineering. Such structures are three-dimensional scaffolds or porous materials that support cells adhesion, proliferation and production of extracellular matrix at a rate that ideally should match the scaffold degradation.

[EN] In this study, chitosan (CH) nanoparticles were obtained by means of cross-linking with sodium tripolyphosphate (TPP). The effect of the concentration, the molecular weight of the CH and the ratio CH:TPP on the physicochemical properties of the obtained dispersions was evaluated. CHbased nanoparticles showed a spherical microstructure.
