Abstract

Organic biosensors are a class of devices specifically designed for the detection and quantification of bioanalytes and/or chemical-physical parameters whose variations occur within a biologically relevant environment. They provide the electronic transduction of chemico-physical properties by means of devices that, thanks to the peculiar properties (i.e., mechanical flexibility, ionic conductance) of organic materials, are biocompatible in a very broad sense, i.e., not only safe for biological tissues but also because they share with them a complete material affinity. For this reason, they are revolutionizing the world of biosensors, paving the way to a variety of novel tools for applications including electrophysiology, bioanalytical chemistry, brain-machine interfaces.
