Conjugated Polymers in Bioelectronics [PDF]

Accounts of Chemical Research, 2018
The emerging field of organic bioelectronics bridges the electronic world of organic-semiconductor-based devices with the soft, predominantly ionic world of biology. This crosstalk can occur in both directions. For example, a biochemical reaction may change the doping state of an organic material, generating an electronic readout.
