However, based on some reports concerning allergic reaction, there has been increasing attention to search similar biomaterials with lower allergenic potential. Therefore, the present work, evaluated the potential of manganeira latex aiming a biomedical and technological applications. Biomembranes were prepared in a controlled manner, and were evaluated for their physical-chemistry characterization (FTIR, CHN, and TG) and its potential as a host matrix for photoluminescent compounds. Furthermore, bioassays were carried out of cell viability and genotoxicity. The results show that mangabeira biomembranes ares structurally similar to seringueira's and also show potential for use in biomedical and technological areas. / Nos últimos anos o látex de seringueira tem recebido grande atenção da comunidade científica, particularmente por suas aplicações biomédicas, as quais podem promover regeneração de tecidos, liberação de fármacos, dentre outros. Entretanto, baseado em alguns relatos sobre reações alérgicas, tem-se despertado interesse pela busca de biomateriais similares com menor potencial alergênico. Desta forma, no presente trabalho, foram avaliadas as potencialidades do látex de mangabeira visando aplicações tanto biomédicas quanto tecnológicas. Foram elaboradas biomembranas de forma controlada, e avaliados sua caracterização físico-química (FTIR, CHN e TG) e seu potencial como matriz hospedeira para compostos fotoluminescente. Além disso, foram realizados ensaios biológicos de viabilidade celular e genotoxicidade. Os resultados mostram que biomembranas de mangabeira são estruturalmente similares às de seringueira e com potencial para uso em áreas biomédicas e tecnológicas
