TI  - Freestanding polyelectrolyte films as sensors for osmotic pressure.

AB  - Freestanding ultrathin polyelectrolyte-multilayer membranes, transferred to 
      topographically structured polydimethylsiloxane (PDMS), are used as mechanical 
      sensors. Due to the membranes' semipermeability, high-molecular-weight molecules 
      can be either entrapped inside them or excluded, thus generating an osmotic 
      pressure. This leads to a deformation. We investigate the deformation as a 
      function of the osmotic pressure and present an analytical theory that fully 
      describes the data. Thus, osmotic pressures can be determined quantitatively. The 
      individual osmotic-sensitive elements have only microscopic dimensions, and 
      arrays can be easily produced.
