Fluidic systems for electrochemical characterization of nanostructured materials synthesized in bulk

Original language description

In recent years, nanotechnology and nanostructured materials (conductive polymers, grafene, gold nanoparticles etc.) have experienced rapid development and penetrated into our everyday lives in multiple areas. One of the areas where nanostructured materials play and will play an important role is point-of-care diagnostics and analysis. Here, they are mostly used for biosensing (proteins, nucleic acids, sugars etc.) but also for separation of targets to be detected often in connection with electrical field. It is thus of utmost importance to have a tool for simple, reliable and rapid characterization of these materials and their identification. In our lab, we are developing a fluidic electrochemical system which allows to characterize nanostructured materials in the form of a bed localized on a supporting filter. This arrangement exploits large interfacial surface of nanostructurated materials. Initial experiments are focused on characterization of nanostructured polypyrrol (conductive polymer) in the form of nanorods, nanowires, and nanotubes by electrochemical impedance spectroscopy. We also study interactions of selected biomolecules with polypyrrole and the effect of these molecules on measured electrical signal. In this paper, we will present our technical solution of the experimental system and selected experimental results obtained for polypyrrole nanostructures.
