Processing of nanomaterials in Layer-by-Layer films: Potential applications in (bio)sensing and energy storage

Abstract: The study and preparation of new nanostructures involving the integration of distinct nanomaterials have been important for the development of new electrochemical devices for (bio)sensing and energy storage. Such devices envisage miniaturized or flexible electronic equipment for emerging technologies, including adaptive displays, artificial skin and wearable devices. In this way, the processing of specific nanomaterials may lead to nanostructures with properties that permit the fabrication of multifunctional devices for different applications, including sensors and supercapacitors. Therefore, the use of a suitable method to manipulate nanomaterials in a same nanostructure is important for this purpose. Thus, we expect that this review provides the readers with a brief overview of the potential usage of the Layer-by-Layer technique to fabricate nanostructured films and their advantages for sensing and energy storage.
