Abstract in another language

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 deformotion as a function of the osmotic pressure and present an analytical theory that fully describes the data. Thus, osmotic pressures con be determined quantitatively. The individual osmotic-sensitive elements have only microscopic dimensions, and arrays con be easily produced.
