Resumen

Tissue engineering has focused on the development of biomaterials, modulating the
morphological and electrochemical characteristics based on their final application. In this setting, the purpose of the present study was to determine the physicochemical response of electrospun
membranes of silk fibroin extracted from sericulture wastes and their functionalization with choline
based bio-ionic liquids. A comparative study of their response was carried out with membranes
obtained from the same protein but functionalized with gold nanoparticles. The biomaterials
developed were characterized by UV-Visible spectrophotometry, FTIR spectroscopy, electron
microscopy (SEM and FESEM), dynamic light scattering (DLS), and Linear sweep voltammetry. The
results obtained showed a fibrillar morphology and the conduction of electrical stimuli by the
membranes functionalized with the gold nanoparticles or the bio-ionic liquids, where for the latter
the response is modulated by the concentration used in the development of the biocomposite.
