Abstract

MéTODO PARA A PRODUçãO DE SULFATO DE CELULOSE (CS) SUBSTITUìDO REGIO-SELETIVO (CS). A invenção refere-se a um método para a produção de sulfato de celulose que é completamente solúvel em água e tem uma viscosidade de solução ajustável em solução aquosa, que qualifica o sulfato de celulose sódico (SCS) produzido como material auxiliar com compatibilidade biológica ideal para aplicações biológicas e médicas, e particularmente é apropriado para a encapsulação e a imobilização de objetos biológicos, por exemplo, tecidos, células, microorganismos, enzimas ou vírus, na microcápsula.
