Fabrication of clamped-clamped beam resonators with embedded fluidic nanochannel

Philippe Renaud, Stefano Silvio Giovanni Varricchio, Luis Guillermo Villanueva Torrijo, Stefano Stassi, Damien Maillard, Annalisa De Pastina, Davide Scaiola, Carlo Ricciardi

Suspended nanochannel resonators (SNRs) are promising devices able to characterize mass down to the attogram scale, thus being able to detect nanoparticles or biomolecules. In this paper, we present a flexible fabrication process for SNRs based on a sacrif ...

Multimaterial Nanoporous Membranes Shaped through High Aspect-Ratio Sacrificial Silicon Nanostructures

Philippe Renaud, Arnaud Bertsch, Stefano Silvio Giovanni Varricchio, Niccolo Piacentini

We present an innovative fabrication method for solid-state nanoporous membranes based on the casting of sacrificial silicon nanostructures. The process allows the individual definition of geometry and placement of each nanopore through e-beam lithography ...

Fabrication of nanoporous membranes through silicon templates : two different approaches

Philippe Renaud, Arnaud Bertsch, Stefano Silvio Giovanni Varricchio, Niccolo Piacentini

We present here a novel approach to fabricate nanoporous membranes based on the use of sacrificial template structures to individually define pore parameters such as geometry, shape, and placement. Based on this rationale two different nano-fabrication met ...

Fabrication of multilayered nanofluidic membranes through silicon templates

Stefano Silvio Giovanni Varricchio

We present a new fabrication method for solid-state nanoporous membranes based on sacrificial template structures made of silicon. The process consists of creating membranes by evaporating thin-films on sacrificial templates which, after their selective re ...
