Cell shape-dependent early responses of fibroblasts to cyclic strain

Jürgen Brugger, Mattia Marelli

Randomly spread fibroblasts on fibronectin-coated elastomeric membranes respond to cyclic strain by a varying degree of focal adhesion assembly and actin reorganization. We speculated that the individual shape of the cells, which is linked to cytoskeletal ...

Silicon nanoparticles synthesized in SiO2 pockets by stencil-masked low energy ion implantation and thermal annealing

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

We propose an original approach called a "stencil-masked ion implantation process" for performing a spatially localized synthesis of a limited number of Si nanocrystals within a thin SiO2 layer. In this process, the SiO2 layer is irradiated with 1 keV sili ...
