Important contributions to the performance of such bioelectrochemical devices have been made based on the integration and supramolecular organization of redox-Active polyelectrolyte-surfactant complexes on electrode supports. Here, we examine the influence of the processing solvent on the interplay between the supramolecular mesoorganization and the bioelectrochemical properties of redox-Active self-Assembled nanoparticle- polyelectrolyte-surfactant nanocomposite thin films. Our studies reveal that the solvent used in processing the supramolecular films and the presence of metal nanoparticles not only have a substantial influence in determining the mesoscale organization and morphological characteristics of the film but also have a strong influence on the efficiency and performance of the bioelectrochemical system. In particular, a higher bioelectrochemical response is observed when nanocomposite supramolecular films were cast from aqueous solutions. These observations seem to be associated with the fact that the use of aqueous solvents increases the hydrophilicity of the film, thus favoring the access of glucose, particularly at low concentrations. We believe that these results improve our current understanding of supramolecular nanocomposite materials generated via polyelectrolyte-surfactant complexes, in order to use the processing conditions as a variable to improve the performance of bioelectrochemical devices. © 2016 American Chemical Society. 2017 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_19448244_v9_n1_p1119_Cortez http://hdl.handle.net/20.500.12110/paper_19448244_v9_n1_p1119_Cortez |
