Complex Modulus of Pdms and Its Application in Cellular Force Measuremes


ABSTRACT Cellular contraction is often accompanied by oscillatory motion of several Hz. Accurate force measurement using Polydimethylsiloxane (PDMS) micropillar based bio-transducers calls for the appropriate material characterization of PDMS in the frequency domain. In this work, the complex modulus of PDMS was measured using a dynamic nanoindentation… (More)
