The ScienceDaily article Faulty Brain Wiring May Be Bypassed With Carbon Nanotubes said
Research done by scientists in Italy and Switzerland has shown that carbon nanotubes may be the ideal “smart” brain material. Their results, published in the journal Nature Nanotechnology, are a promising step forward in the search to find ways to “bypass” faulty brain wiring.
The research shows that carbon nanotubes, which, like neurons, are highly electrically conductive, form extremely tight contacts with neuronal cell membranes. Unlike the metal electrodes that are currently used in research and clinical applications, the nanotubes can create shortcuts between the distal and proximal compartments of the neuron, resulting in enhanced neuronal excitability.
The study was conducted in the Laboratory of Neural Microcircuitry at EPFL in Switzerland and led by Michel Giugliano (now an assistant professor at the University of Antwerp) and University of Trieste professor Laura Ballerini. “This result is extremely relevant for the emerging field of neuro-engineering and neuroprosthetics,” explains Giugliano, who hypothesizes that the nanotubes could be used as a new building block of novel “electrical bypass” systems for treating traumatic injury of the central nervous system.
Michele Giugliano, Ph.D. is
presently tenure-track professor at the Department of Biomedical
Sciences of the University of Antwerp (Belgium) and visiting scientist
at the Brain Mind Institute of the EPFL, the Ecole Polytechnique
Fédérale
de Lausanne (Switzerland).
He is originally from Italy,
where he was
trained as an Electronic Engineer. He earned his 5 years
laurea-degree
cum laude from the University of Genova in 1997. During the following
years, he
developed a strong interest in Computational Neuroscience and in 2001 he
was awarded by the Politecnico di Milano (Italy) with a Ph.D. in
Bioengineering.
In the same year, Michele received a long-term
fellowship from
the Human Frontier Science Program Organization, to pursue experimental
research on the nervous system, with emphasis on novel non-conventional
experimental paradigms and techniques. He moved to the Faculty of
Medicine of the University of Bern (Switzerland), as a member of the
Department of Physiology. From 2005 to 2008, he has been Junior Group
Leader at the Brain Mind Institute of the EPFL.
His research interests include in vitro electrophysiology, exploring
network-level phenomena in neocortical brain slices and dissociated
cell cultures. In particular, he explores the combination of
non-conventional stimulating/recording tools and nanomaterials (e.g.
multi-electrode substrate arrays MEAs) with traditional
patch-clamp
recording techniques. These activities are driven and supported by
computer-simulations and theoretical analysis tools, involving models of
single-cells and networks of spiking neurons.
His research interests are related to understanding, repairing,
replacing, enhancing, or exploiting the electrical properties of neural
systems. With particular emphasis to the (bio)physics of the interface
between living neural tissue and artificial constructs, his efforts are
aimed at exploring experimentally the predictions of theoretical
approaches, employing them to design novel experimental paradigms and to
analyze and interpret experimental data. Recently, in collaboration with
other researchers, he became interested in combining carbon nanotubes to
neuronal networks, as a first step towards future generation
neuroprosthetics.
