The standard TopSpot technology has been successfully used in the recent years for the highly parallel nanoliter dispensing of bio-chemical substances for microarray printing. It is based on a pneumatically actuated printhead which enables non-contac

We present a novel, cost-efficient process chain for fast tooling and small-lot replication of high-quality, multi-scale microfluidic polymer chips within less than 5 days. The fabrication chain starts with a primary master which is made by well-esta

We present a new method for the highly-parallel and simultaneous delivery of a multitude of reagents in the picolitre range. This method is based on direct displacement of the liquids using an elastomer-stamp, which simultaneously actuates up to 96 d
