Surface modification of bacterial cellulose by nitrogen-containing plasma for i...
Pértile, Renata Aparecida Nedel; Andrade, Fábia K.; Alves Junior, Clodomiro; Gama, F. M.Bacterial cellulose (BC) membranes were modified with nitrogen plasma in order to enhance cell affinity. The surface properties of the untreated and plasma modified BC (BCP) were analyzed through contact angle measurements, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The effect of the plasma treatment on the adhesion of microvascular (HMEC-1), neuroblast (N1E-115) and fibrobla...
BC nanofibres: in vitro study of genotoxicity and cell proliferation
Moreira, Susana Margarida Gomes; Silva, Naisandra Bezerra; Almeida-Lima, Jailma; Rocha, Hugo Alexandre Oliveira; Medeiros, Silvia Regina BatistuzzoNanomaterials have unusual properties not found in the bulk materials, which can be exploited in numerous applications such as biosensing, electronics, scaffolds for tissue engineering, diagnostics and drug delivery. However, research in the past few years has turned up a range of potential health hazards, which has given birth to the new discipline of nanotoxicology. Bacterial cellulose (BC) is a promising mat...
