Abstract

SÍNTESE DE CARBOXICELULOSE NANOESTRUTURADA DE CELULOSE NÃO LENHOSA. É aqui revelado um processo aperfeiçoado para a preparação de carbóxi celulose nanoestruturada oxidada com alto teor de carbóxi e alto rendimento, por sujeição de lignocelulo se não lenhosa, (Alfa)-celulose derivada de bagaço de cana de açúcar, ou celulose de algodão, a oxidação à temperatura adequada, no qual a forma da partícula é esférica, o tamanho de partícula da carbóxi celulose sintetizada é na faixa de 1-100 nm, e o grau de polimerização (DP) é na faixa de 50-70. Adicionalmente, a presente invenção proporciona composição farmacêutica compreendendo carbóxi celuloses nanoestruturadas oxidadas, preferivelmente, 6-carbóxi celulose, e 2,3,6- tricarboxicelulose, sozinhas ou em associação com um ou mais transportador(es) farmaceuticamente aceitável(is), ou excipiente(s), para tratamento de infecção microbial. As carboxiceluloses foram eficientes na estabilização de nanotubos de carbono de paredes múltiplas e nanotubos de carbono de parede única em meio aquoso.
