A bimetallic nanocoral Au decorated with Pt nanoflowers (bio)sensor for H2O2 detection at low potential

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Francesca Puppo

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 ...

SiNW-based Biosensors for Profiling Biomarkers in Breast Tumor Tissues

Francesca Puppo

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 ...

Surface trap mediated electronic transport in biofunctionalized silicon nanowires

Giovanni De Micheli, Sandro Carrara, Francesca Puppo, Massimiliano Di Ventra

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 ...

Memristor-Based Devices for Sensing

Giovanni De Micheli, Sandro Carrara, Francesca Puppo, Massimiliano Di Ventra

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 ...

Memristive Biosensors Under Varying Humidity Conditions

Giovanni De Micheli, Sandro Carrara, Davide Sacchetto, Yusuf Leblebici, Camilla Baj-Rossi, Francesca Puppo, Akshat Dave

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 ...

High Sensitive Detection in Tumor Extracts with SiNW-FET in-Air Biosensors

Giovanni De Micheli, Sandro Carrara, Francesca Puppo

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 ...
