Multi-Wire Tri-Gate Silicon Nanowires Reaching Milli-pH Unit Resolution in One Micron Square Footprint

Luca Selmi, Enrico Accastelli, Carlotta Guiducci, Thomas Ernst, Paolo Scarbolo, Pierpaolo Palestri

The signal-to-noise ratio of planar ISFET pH sensors deteriorates when reducing the area occupied by the device, thus hampering the scalability of on-chip analytical systems which detect the DNA polymerase through pH measurements. Top-down nano-sized tri-g ...

Analysis of Dielectric Microbead Detection by Impedance Spectroscopy with Nanoribbons

Luca Selmi, Enrico Accastelli, Carlotta Guiducci, Thomas Ernst, Paolo Scarbolo

We present a quantitative numerical analysis of dielectric microbead detection experiments with nanoribbons operated in the AC small signal regime. To this purpose, a comprehensive model of nanoribbon operation in electrolyte environment and with DC/AC sig ...

Tri-gate silicon nanowire transistors for ultra-low pH resolution and improved scalability

Enrico Accastelli

The scalability of on-chip analytical systems based on field-effect transistors as pH sensors is limited by the degradation of the signal to noise ratio when decreasing the device size. Nano-sized tri-gate transistors such as silicon nanowires and nanoribb ...
