compósito de colágeno e nanotubos de carbono e seu processo de obtenção. a presente invenção descreve um processa de fabricação de um material biocompósito biodegradável usando colágeno e nanotubos de carbono. ele pode ser usado para aplicações em áreas médicas e veterinárias visando regeneração, reposição e reconstituição celular ou de tecido biológico, invitro ou in-vivo. este material é de reconhecida biocompatibilidade, resistência mecânica estrutural, biodegradabilidade, baixa citoxicidade, alta hemástase, capacidade de induzir, de estimular processos de crescimento celular e de regeneração de tecidos, além de servir para liberação controlada de drogas, carreamento local de radiofármacos e substâncias citotáxicas em aplicações e procedimentos de tratamentos de câncer. The present invention refers to a process for preparing a biodegradable, biocomposite using collagen and carbon nanotubes. It can be used in the in medical and veterinary areas, for the purpose of regenerating, replacing and reconstituting cells and biologic tissue, either in vitro or in vivo. This composite shows biocompatibility, structural mechanical strength, biodegradability, low cytotoxicity, high hemostasis, capability of inducing and stimulating cell growth and tissue regeneration, besides serving for drugs controlled releasing, local carrying of radiopharmaceuticals and citotoxic substances in several therapeutic applications and procedures, such as cancer therapy.
