Liquid polystyrene: a room-temperature photocurable soft lithography compatible pour-and-cure-type polystyrene

In this paper we introduce “liquid polystyrene,” a castable photocurable polystyrene prepolymer, for microfluidic prototyping. Using this material, polystyrene, an important polymer in cell biology will become accessible via soft lithography replication.

Micropatterned biofilm formations by laminar flow-templating

We present a flow-templating micro-bioreactor as a new concept for controlled patterning of linear biofilm formations. Experiments and simulations comprehensively exploit control parameters to grow biofilm patterns with controllable dimensions. The paper concludes with a study of biofilm growth rates under well-defined shear stress environments.
