Nanoscale hydrophobic coatings for the separation of liquid mixtures

Truman P., Frenzel R., Longari N., Uhlmann P., Stamm M., Institute of Polymer Research, DE

Organofunctional nanoscale silane coatings are widely used to modify surface chemistry. Such coatings have many applications in micro- and nanofluidics because liquid motion on these scales is strongly influenced by capillary or wall effects. In [...]

Liquid transport detection using single FET devices

Truman P., Uhlmann P., Stamm M., Institute of Polymer Research, DE

Observation and monitoring liquid transport and transport in liquids is a major task for lab on a chip applications and research. We use novel thin film FET devices based on silicon-on-insulator (SOI) substrates as planar [...]

Separation dynamics of binary liquid mixtures – Theory & Experiment

Truman P., Varnik F., Uhlmann P., Stamm M., Raabe D., Institute of Polymer Research, DE

We study how chemically patterned surfaces can be applied for the separation of two incompatible liquids and introduce a novel simplified separation scheme utilizing surfaces with an abrupt change of surface energy. Firstly we analyse [...]
