We present a theoretical framework for the calculation of charge transport through nanowire-based Schottky-barrier field-effect transistors that is conceptually simple but still captures the relevant physical mechanisms of the transport process. Our approach combines two approaches on different length scales: (1) the finite element method is used to model(More)
Here we propose a platform for the detection of unlabeled human α-thrombin down to the picomolar range in a fluorescence-based aptamer assay. In this concept, thrombin is captured between two different thrombin binding aptamers, TBA1 (15mer) and TBA2 (29mer), each labeled with a specific fluorescent dye. One aptamer is attached to the surface, the second(More)
The conjunction of miniature nanosensors and droplet-based microfluidic systems conceptually opens a new route toward sensitive, optics-less analysis of biochemical processes with high throughput, where a single device can be employed for probing of thousands of independent reactors. Here we combine droplet microfluidics with the compact silicon nanowire(More)
