  • The sensing capability of nanometric transducers designed for label-free single molecule detection has been limited by the small number of recognition elements. Here, the authors demonstrate a millimetre-sized field effect transistor capable of selective single-molecule Immunoglobulin-G detection.

  • Organic bioelectronic devices can be used to convert biological recognition events to a signal output. Here, the authors show how a water gated field-effect transistor modified with odorant binding proteins can be used to analyse the enantioselectivity of carvone binding and also estimate free-energy changes.

  • Potentiometric immunoassays using field-effect transistors offer ultrasensitive protein detection for point-of-care and early diagnostics. This Perspective introduces a framework distinguishing a double-layer regime active at nanomolar antigen concentrations and a ΔpH-enabled regime active at sub-femtomolar concentrations, and examines the potential underlying mechanisms.

  • Chiral detection using organic sensors has been limited to concentration levels of parts-per-thousand. The use of a thin-film transistor and of semiconducting oligomers with chiral side arms improves differential detection of enantiomers to parts per million.

  • Electrolyte-gated transistors (EGTs) are fundamental building blocks of bioelectronics, which transduce biological inputs to electrical signals. This Primer examines the different architectures of EGTs, their mechanism of operation and practical considerations related to their wide range of applications.
