We present a new technique to characterize the elastic properties of a thin biological membrane. An effective instrument that embodies video enhanced microscope was developed primarily to provide the capability of simultaneously measuring both the applied force and the resultant displacement of the biological membrane under a central point force. A theoretical linear elastic solution was applied to...
We present a new method to characterize the viscoelastic properties of a thin polymeric film. A sensitive microscope visualization instrument was used for measuring the time-dependent deformation, i.e. creep, of the circular thin membrane under a constant load. The elastic deformation of the thin membrane was measured laterally. The elastic modulus as a function of time can be explicitly determined...
