We propose ion-induced dewetting of Au thin films as a mechanism to modify and control the morphology of Si nanowires formed through metal-assisted chemical etching. We show that the patterns formed upon irradiation resemble those typical of dewetting phenomena, with a characteristic length in the nanometer range. Irradiated Au films are then...

In the last years, nanopore technology has been increasingly exploited for biomolecule detection andanalysis. Recently, the main focus of the research has moved from the study of nucleic acids to theanalysis of proteins and DNA-protein complexes. In this paper, chemically functionalized solid-statenanopore has been used to recognize Nuclear...

We exploit the fabrication capabilities of the Ultra High Resolution Field Emission Scanning Electron Microscopy (UHR-FE-SEM) and Focused Ion Beam (FIB), model CrossBeam® 1540XB by Zeiss, equipped with EDX, GIS, and STEM modules, in order to mill a silicon master for a first step of a wider project of designing, developing, and producing of...

We present the first detailed experimental observation and analysis of nanoparticle electrophoresis through a nanochannel obtained with synchronous high-bandwidth electrical and camera recordings. Optically determined particle diffusion coefficients agree with values extracted from fitting electrical transport measurements to distributions from...

The lack of engineering systems able to faithfully reproduce complex kidney structures in vitro has made it difficult to efficiently model kidney diseases and development. Using polydimethylsiloxane (PDMS) scaffolds and a kidney-derived cell line we developed a system to rapidly engineer custom-made 3D tubules with typical renal epithelial...
