A neuron-silicon junction: a Retzius cell of the leech on an insulated-gate field-effect transistor.
TL;DR: An identified neuron of the leech, a Retzius cell, has been attached to the open gate of a p-channel field-effect transistor, and weak signals that resemble the first derivative of the action potential were observed.
Journal ArticleDOI
Labelfree fully electronic nucleic acid detection system based on a field-effect transistor device
F. Uslu,Sven Ingebrandt,Dirk Mayer,Simone Böcker-Meffert,Margarete Odenthal,Andreas Offenhäusser +5 more
TL;DR: An approach to detect the hybridisation of DNA sequences using electrolyte-oxide-semiconductor field-effect transistors (EOSFETs) with micrometer dimensions and results indicate that the sensor output is charge sensitive and distance dependent from the gate surface, which pinpoints the need for very defined surface chemistry at the device surface.
Journal ArticleDOI
Possibilities and limitations of label-free detection of DNA hybridization with field-effect-based devices
Arshak Poghossian,Andrey G. Cherstvy,Sven Ingebrandt,Andreas Offenhäusser,Michael J. Schöning +4 more
TL;DR: In this paper, a new DNA-detection method is introduced, which utilizes an ion-sensitive field-effect device as transducer, based upon the DNA hybridization induced redistribution of the ion concentration within the intermolecular spaces and/or the alteration of the Ion sensitivity of the device is proposed as detection mechanism.
Journal ArticleDOI
Graphene Transistor Arrays for Recording Action Potentials from Electrogenic Cells
Lucas H. Hess,Michael Jansen,Vanessa Maybeck,Moritz V. Hauf,Max Seifert,Martin Stutzmann,Ian D. Sharp,Andreas Offenhäusser,Jose A. Garrido +8 more
TL;DR: The development of the future generation of neuroprosthetic devices will require the advancement of novel solid-state sensors and actuators with a further improvement in the signal detection capability, a superior stability in biological environments, and a more suitable compatibility with living tissue.
Journal ArticleDOI
Field-effect transistor array for monitoring electrical activity from mammalian neurons in culture
TL;DR: It can be shown that the microelectronic device surface can be modified with a synthetic peptide linked to the surface and allows hippocampal neurons to adhere and grow for days.
