Electrolyte-Gated Organic Field-Effect Transistor Sensors Based on Supported Biotinylated Phospholipid Bilayer

adv 1An electrolyte gated organic field-effect transistor (EGOFET) endowed with a biological capturing layer can allow high performance electronic biodetection in a high ionic strength buffer solution as reported by Luisa Torsi, Gerardo Palazzo and co-workers on page 2090. The cover image illustrates flexible electronic circuits printed on a protein strand, imaginatively featuring the ultimate integration of the two systems. Inside Front Cover Image: Daniele Romeo.

Hydrogen-Bonded Semiconducting Pigments for Air-Stable Field-Effect Transistors

adv 2Perhaps the same materials used in printer inks and hair dyes can be employed in future electronic technologies? The front cover illustrates the use of hydrogen-bonded pigments, well-established printing inks, in organic electronic circuits. On page 1563, Eric Daniel Głowacki and co-workers present a new perspective for the design of stable organic semiconducting molecules based on intermolecular π-stacking reinforced by hydrogen-bonding bridges. Front Cover Image design: Georg Wieser, WIEsuell-3D Animation & Multimedia, Austria.

Surface architectures for analytical purposes

surface articleReviews critically discuss crucial issues which affect more or less all classes of sensors and in some cases still limit their performances and/or prevent their use in real life; important aspects of these are immobilization of the recognition element, which should preserve its chemical and/or biological functionality, and the integration between recognition element and transducer. Moreover, insights are provided on problems related to miniaturization, stability, reliability, and lowcost production, and future perspectives for each class of sensing device are emphasized.

Effect of morphology on organic thin film transistor sensors

analyticalchemistry 2This review provides a general introduction to organic field-effect transistors and their application as chemical sensors. Thin film transistor device performance is greatly affected by the molecular structure and morphology of the organic semiconductor layer. Various methods for organic semiconductor deposition are surveyed. Recent progress in the fabrication of organic thin film transistor sensors as well as the correlation between morphology and analyte response is discussed.
