AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

The sensitive analysis of proteins is central to disease diagnosis. The detection and investigation of angiogenic and inflammatory ligands in the tumor tissue can further improve the level of knowledge of the cancer disease by capturing the heterogeneity a ...

Breast cancer is the most common life-threatening malignancy in women of most developed countries today, with approximately 200,000 new cases diagnosed every year. About 30% of these cases progress to metastatic disease and death. Considering that one-thir ...

We present a novel circuit for the automated and quick characterization of an array of experimental memristive nanowires that are functionalized as biosensors. Successfully functionalized nanowires will express the concentration of target molecules by hyst ...

In this paper we propose CMOS-compatible Memristive-Biosensors as label-free, highly sensitive sensors for in-air detection of Vascular Endothelial Growth Factor (VEGF) molecules. The memristive behavior of the fabricated devices is strongly affec ...

We attempt to examine the potential of silicon nanowire memristors in the field of nanobiosensing. The mem- ristive devices are crystalline Silicon (Si) Nanowires (NWs) with Nickel Silicide (NiSi) terminals. The nanowires are fabricated on a Silicon-on-Ins ...

Silicon nanowires (SiNWs), fabricated via a top-down approach and then functionalized with biological probes, are used for electrically-based sensing of breast tumor markers. The SiNWs, featuring memristive-like behavior in bare conditions, show, in the pr ...

In this paper, a complete study is carried out investigating the relationship between the biosensing and the electrical characteristics of freestanding two-terminal Schottky-barrier silicon nanowires. This paper successfully reproduces computationally the ...

The integration of nanoscale sensors with microfluidic platforms is a powerful tool for the design of robust biosensing devices that present high reliability and the advantage of a quick data acquisition. In addition, microfluidic based lab-on-a-chip senso ...

We have already demonstrated that high quality SiNW-FETs can be used to sense very low concentration range (fM) of pathogenic factors in controlled PBS. In this work we show, for the first time, Silicon Nanowire Field Effect Transistors (SiNW-FET) as biose ...

In the present work, a computational study is carried out investigating the relationship between the biosensing and the electrical characteristics of two-terminal Schottky- barrier silicon nanowire devices. The model suggested successfully reproduces compu ...

In this work, we have developed for the first time a method to make novel gold and platinum hybrid bimetallic nanostructures differing in shape and size. Au-Pt nanostructures were prepared by electrodeposition in two simple steps. The first step consists o ...

A large progress in pH sensing with nanowire based ion-sensitive field-effect transistors (ISFETs) has been demonstrated over the years. The electrochemical reactions occurring at the wire surface-to-electrolyte interface play a key role in the detection o ...
