Fabrication of clamped-clamped beam resonators with embedded fluidic nanochannel

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

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 ...

Electrostatically gated nanofluidic membranes: Technological developments and use of electrochemically polarizable materials

Stefano Silvio Giovanni Varricchio

Solid-state nanoporous membranes able to control ionic flows at the molecular level could have important applications in fields of research such as water filtration, nanomedicine, energy production, drug delivery, and bio-chemical analysis. The ability to ...

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

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

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 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 ...

Fabrication of nanoporous membranes through silicon templates : two different approaches

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

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 ...
