Solid-state Nanopore Array Membranes Patterned by Electron Beam Lithography, Nanosphere Lithography and Aluminum Anodization

Jürgen Brugger, Andreea Veronica Savu, Nicolas Blondiaux, Songmei Wu, Oscar Vazquez Mena, Mona Julia Katharina Klein, Vaida Auzelyte, Franck Montagne

We present the fabrication of thin membranes with dense arrays of nanometer and submicrometer pore arrays by the integration of standard micromachining with three pore patterning techniques: electron beam lithography (EBL), nanosphere lithography (NSL) and ...

Dynamical membrane curvature instability controlled by intermonolayer friction

Anne-Florence Raphaëlle Bitbol

We study a dynamical curvature instability caused by a local chemical modification of a phospholipid membrane. In our experiments, a basic solution is microinjected close to a giant unilamellar vesicle, which induces a local chemical modification of some l ...

HEATED MEMBRANES PREVENT CLOGGING OF APERTURES IN NANOSTENCIL LITHOGRAPHY

Jürgen Brugger, Andreea Veronica Savu, Shenqi Xie

We demonstrate a novel concept for nanostencil lithography with an integrated microhotplate on the stencil membrane aimed at eliminating or reducing aperture clogging during metal deposition. The stencil can be locally heated up by the embedded Pt coils to ...

Universal amplitudes of the Casimir-like interactions between four types of rods in fluid membranes

Anne-Florence Raphaëlle Bitbol

The fluctuation-induced, Casimir-like interaction between two parallel rods of length L adsorbed on a fluid membrane is calculated analytically at short separations d < L. The rods are modeled as constraints imposed on the membrane curvature along a strai ...

Dynamically deformable micromirror array for defined laser beam shaping and homogenizing

Nico de Rooij, Roland Andreas Bitterli, Jonathan Masson, Wilfried Noell

We present a dynamic laser beam shaper than can generate smooth flat top and gaussian intensity profiles. It consists of a 100% fill factor membrane, supported by beams or posts, that deforms in a shape similar to a concave linear or 2D microlens array. Th ...

Interactions and Reactivity at Liquid-Liquid Interfaces

Manuel Alejandro Méndez Agudelo

The interface between two immiscible electrolyte solutions (ITIES) provides a well-defined platform for fundamental studies of adsorption processes and molecular reactivity in general. Two bio-inspired systems are considered in the present work: adsorbed p ...

Chaotic mixing using source-sink microfluidic flows in a PDMS chip

Martinus Gijs, Abdeljalil Sayah, Caroline Vandevyver, Hüseyin Cumhur Tekin, Ata Tuna Ciftlik, Venkataragavalu Sivagnanam

We present an active fixed-volume mixer based on the creation of multiple source–sink microfluidic flows in a polydimethylsiloxane (PDMS) chip without the need of external or internal pumps. To do so, four different pressure-controlled actuation chambers a ...

Reliable and Improved Nanoscale Stencil Lithography by Membrane Stabilization, Blurring and Clogging Corrections

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Andreea Veronica Savu, Oscar Vazquez Mena, Katrin Sidler Arnet

Abstract— The reliable and reproducible fabrication of nanostructures by stencil lithography faces three main challenges: the stability of the thin stencil membranes with nanoapertures, the blurring of the deposited structures, and the clogging of the nano ...
