IRIS Institutional Research Information System - OPENBS Open Archive UniBS
il nuovo catalogo dedicato alla raccolta e alla disseminazione della produzione scientifica dell'Università degli Studi di
Brescia, denominato OPENBS. E' possibile cercare pubblicazioni in OPENBS:
- per parola chiave, utilizzando la barra di ricerca situata in alto
- per filtro di ricerca (Autore, Titolo, Riviste), utilizzando il pulsante Sfoglia
- specificando criteri di ricerca con possibilità di aggiungere gradualmente più filtri (Autore, Data, Tipologia,..) che
perfezionino i risultati, utilizzando la finestra Ricerca - per elemento di filtro di ricerca (e.g. per un elemento di Tipologia: contributo su rivista) nella sezione Scopri
EnglishComposites of gelatin, chitosan and conductive carbon black nanoparticles were prepared to realize mechanically robust hydrogels integrating electrically conductive properties. The incorporation of carbon black nanoparticles into the polymer matrix significantly improved mechanical characteristics of the hydrogels, achieving also optimally tunable electrical properties. High water uptake was maintained and increase of mechanical properties, stiffness and strength was obtained. Promising electrical behavior was observed, with distinctive resistivecapacitive transition frequency depending on carbon black content. All these characteristics represent indeed fundamental features required in tissue engineering. The use of coherent mechanical matrix with conductive nanoparticles could allow to tune the electrical characteristics, thus to promote cell growth by means of both mechanical and electrical stimuli.
