Resumo: | Objective: This study produced a fungal chitosan membrane extracted from Rhizopus stolonifer, as well as its modification using dielectric barrier discharge plasma (DBD), aiming to improve the physicochemical characteristics of the membrane, optimizing its use in the medical research field. Method: The obtained chitosan was physically and chemically characterized (Molecular Weight, Fourier Transform Infrared, X-ray Diffraction), later were produced fungal chitosan membranes and DBD plasma was applied. The membranes were characterized before and after plasma application using the tests contact angle, swelling and atomic force microscopy (medium roughness) analyzes. Results: A fungal chitosan with a yield of 16.73 mg/g, and an apparent molecular weight of 4 kDa was obtained, being considered of low molecular weight and high degree of deacetylation (84%). It was possible to obtain the membrane and after application of DBD plasma, the contact angle dropped from 77.5° to 30.9°, making it more hydrophilic. Conclusion: Thus, the efficiency of the technique for increasing the hydrophilicity of the fungal chitosan membrane without the additive of chemical reagents during the process was confirmed and the membrane formed is a promising alternative can be used in different ways in the medical area. |

Método: El quitosano obtenido se caracterizó física y químicamente (Peso Molecular, Transformación de Fourier en infrarrojos, Difracción de Rayos X), posteriormente se produjeron membranas de quitosano fúngico y se aplicó plasma DBD. Las membranas se caracterizaron antes y después de la aplicación del plasma mediante ensayos de ángulo de contacto, hinchamiento y microscopía de fuerza atómica (rugosidad media). Resultados: Se obtuvo un quitosano fúngico con un rendimiento de 16,73 mg / gy un peso molecular aparente de 4 kDa, considerándose de bajo peso molecular y alto grado de desacetilación (84%). Se pudo obtener la membrana y luego de aplicar el plasma DBD, el ángulo de contacto bajó de 77.5 ° a 30.9 °, haciéndola más hidrofílica. Conclusión: Así, se confirmó la eficacia de la técnica para incrementar la hidrofilicidad de la membrana fúngica de quitosano sin la adición de reactivos químicos durante el proceso y la membrana formada es una alternativa prometedora que puede ser utilizada de diferentes formas en el campo médico.Objetivo: Este estudo produziu uma membrana fúngica de quitosana extraída de Rhizopus stolonifer, bem como sua modificação utilizando plasma de descarga de barreira dielétrica (DBD), visando melhorar as características físico-químicas da membrana, otimizando seu uso na área de pesquisa médica.
