Organic Bioelectronic Material
Due to their chemical similarities to biological systems (carbon, oxygen, nitrogen-based composition), organic semiconductors (molecular systems and polymers) are promising bio-interfacing materials offering the prospect of improved compatibility in devices intended for neurophysiological and pathophysiological investigations and applications.
Softness and flexibility of organic materials, as compared to traditional silicon-based electronic materials, offer improved compatibility with neural tissue, whereas the combined ionic and electronic conductivity enables the use of organic electronic devices as direct signals transductors of neural systems.
Organic materials combine the mechanical properties of soft materials with electrical and optical properties suitable for stimulation and read-out of bioelectrical events. Also, large and ultrafast linear and nonlinear optical responses and broad spectral tunability are coupled to solution-processing at low cost, allowing large-area deposition on non-standard substrates.
Within OLIMPIA expertise and know-how on synthesis of polymeric organic semiconductors polymers will be provided (UPV-EHU) and combined synergistically with Organic Optoelectronics and Neuroscience units to provide materials that improve device performances in aqueous physiological environments, enable biocompatibility and controlled cell growth and orientation of neural cells. Particular attention will be devoted to ensure that organic materials and device structures in direct contact with neural cells preserve the physiological cell function and prevent reactive gliosis.
