Dr Benfenati is a pharmacyst, her background is in Neuroscience, Electrophysiology, Neural cell physiology, Ion channel Biophysics, Glial cell physiology. Since 2010 she is coordinating a group working on innovative ad-hoc tailored materials and device platform (bioelectronic and bio photonics) targeting neuroscience fundamental investigation and neurological applications (including neurophotonics, electronics and neuroregenerative medicine). The long term goal our studies is to unravel new mechanisms underpinning brain cell communication mechanisms, by using technologies that enable multiscale probing and control of neural cells function.
A specific aspect of pur research is the study of brain cells called astrocytes.
Astrocytes are the cells that in the brain are devoted to brain homeostasis, that they tighly regulate by membrane ion channels, water channels and receptors. Nonetheless over the past 20 years, it has been established that the classical neurocentric vision in uncomplete. Indeed, the information processes and cognitive function are not relying solely on neurons. With their endfeet astrocytes encompass and regulate synapse. Nonetheless, by intracellular Ca2+ oscillations and waves astrocytes can release neurotrnasmitters and they can sense and orchestrate the response to envitomental stimuli.
However, progress on understanding on astrocytes physiology were hampered by the use of technologies and approached that were developed and targeted to neurons.
To this end Dr Benfenati developed the concept of Glial Inface and glial Engineering to complement with neural interface, and she is validating the use of materials interface, electronic and photonic devices that enable to study of astrocytes with unpresented resolution and with multiscale approach (from nano, single channel, to cell up to sincytium and whole brain).
- She defined slow oscillations in differentiated astrocytes in vitro:
- She defined the ability of IR laser light to excite TRPV4 and TRPA1-mediated calcium signalling and water transport in astrocytes https://faseb.onlinelibrary.wiley.com/doi/full/10.1096/fj.201903049R
- She contribute to the development and validation of the first organic field effect transistor architecture capable to stimulate and record electrophysiological signals from primary neurons O-CST (Benfenati et al., Nat Mater, 2013; see pub list). Results from the work she is coordinating, in synergy with researcher of commessa DIMO-ISMN are putting the basis for novel supradisciplinary field she called organic neuro-optoelectronic.
- She contribute to define functional and molecular interaction between aquaporins and ion channels among which AQP4 and TRPV4, AQP4 and VRAC. (Benfenati et al., PNAS 2011; Benfenati et al., J Neurochem, 2007; Formaggio et al., Faseb J; 2019).
- The group she is leading, in collaboration with researcher at ISOF, ISMN and IBIMET, has also establish an internationally recognized expertise on the silk fibroin. They were able to established in loco at CNR Research Area the entire silk fibroin chain from production of raw-material to assessment for upscaled extraction/purification methodology, to fabrication of tailored biophotonic substrates, nanocomposites and novel multifunctional biomaterials targeted to biophotonic and neuroregenerative medicine.

The major objectives of my research group are
- To unravel new mechanisms underpinning brain cell communication mechanisms
- To exploit bio-functionalities of innovative ad-hoc tailored materials and device platform (bioelectronic and bio photonics) in to monitor and modulate physiological parameters of neural cells (neurons and astrocytes)
- To define bio-activity (in terms of gene, protein molecular and functional expression) of novel synthesized small molecules, drugs, nanodelivery systems, advanced multifunctional materials, biophotonic systems, on membrane water and ion channels which are essential for the biology and physiology of primary brain cells.
- To define and develop the potential of silk fibroin biomaterials platforms, in sustainable and bio-derived technologies for photonics, electronics and biomedicine.
Our mission is to create effective tools for biomedical research biotechnologies and neuroregenerative medicine by contributing to engineering, fabrication and characterization of innovative device based organic biomaterials and field-effect transistor architecture or biophotonics structures that could provide cell/device bidirectional communication with excitable and non-excitable cells of the CNS. Over the past ten years we defined biofunctional and bioactive properties of carbon based, inorganic and hybrid materials platforms deriving from natural or synthetic origin such as silk fibroin, organic semiconductors and lamellar nanoparticles and graphene by state of the art technologies in cellular biology molecular biology and cellular physiology.
The multidisciplinary nature of the topics developed relies on competence of the broad team of researcher involved in the topic that regards on cell and system physiology, neuroscience, neurobiology, chemistry, materials science, device physics, photonics. The different research topics are developed in straight synergy with researchers from other Institutes of the DCSTM and of other Department of CNR as well as with Universities of the Italian Research ecosystem through MIUR FIRB Giovani (UNIBA), Progetto Bandiera (CNR-ISOF, CNR-ISMN, CNR-IBIMET),
The research and innovation beyond the work is supported by the participation and coordination of national and international and transcontinental projects and related collaborations (see ongoing and completed research support). Among the other the support from Air Force Office of Scientific Research and the policy of the US-Italy JS&T commission were essential to seed the research community at international level. The most recent achievement is the EU-Horizon-2020 MSCA ASTROTECH project (www.astrotechproject.eu).
