Automated Real-Time Control of Fluidic Self-Assembly of Microparticles

Jürgen Brugger, Alcherio Martinoli, Massimo Mastrangeli, Felix Stephan Schill, Helmut Knapp

Self-assembly is a key coordination mechanism for large multi-unit systems and a powerful bottom-up technology for micro/nanofabrication. Controlled self-assembly and dynamic reconfiguration of large ensembles of microscopic particles can effectively bridg ...

Acousto-fluidic system assisting in-liquid self-assembly of microcomponents

Jürgen Brugger, Alcherio Martinoli, Massimo Mastrangeli, Rosario Maurizio Gullo, Loïc Jacot-Descombes, Grégory Mermoud, Helmut Knapp

In this paper, we present the theoretical background, design, fabrication and characterization of a micromachined chamber assisting the fluidic self-assembly of micro-electro-mechanical systems in a bulk liquid. Exploiting bubble-induced acoustic microstre ...

Lab-on-a-chip for multiplexed biosensing of residual antibiotics in milk

Yves Leterrier, Guillaume Suarez, Helmut Knapp

A multiplexed immunoassay-based antibiotic sensing device integrated in a lab-on-a-chip format is described. The approach is multidisciplinary and involves the convergent development of a multi-antibiotic competitive immunoassay based on sensitive waveleng ...

Fabrication of metallic patterns by microstencil lithography on polymer surfaces suitable as microelectrodes in integrated microfluidic systems

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Nao Takano, Helmut Knapp

Microstencil lithography, i.e. local deposition of micrometer scale patterns through small shadow masks, is a promising method for metal micropattern definition on polymer substrates that cannot be structured using organic-solvent-based photoresist technol ...
