Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>An organic ultralow voltage field effect transistor for DNA hybridization detection</bold> is presented. The transduction mechanism is based on a field‐effect modulation due to the electrical charge of the oligonucleotides, so label‐free detection can be performed. The device shows a sub‐nanometer detection limit and unprecedented selectivity with respect to single nucleotide polymorphism. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1p8tg8vp" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
