Organic semiconductors for light-mediated neuromodulation

Abstract

AbstractOrganic semiconductors have generated substantial interest in neurotechnology and emerged as a promising approach for wireless neuromodulation in fundamental and applied research. Here, we summarise the range of applications that have been proposed so far, including retinal stimulation, excitation and inhibition of cultured neurons and regulation of biological processes in other non-excitable cells from animal and plant origins. We also discuss the key chemical and physical phenomena at the basis of the interaction between materials and cells. Finally, we provide an overview of future perspectives, exciting research opportunities and the remaining challenges hampering the translation of this blooming technology into the clinic and industry.
