Abstract
We report also an experiment that allows to mimic the mechanical environment of cells in tissues. Micro-meter sized beads are trapped in circular geometry in order to surround living cells. By dynamically varying the geometry of the configuration and the trapping forces, we can reproduce a controlled environment where only mechanical stimuli are present and biological responses can be monitored. These experiments have been implemented in two different setups. In the first, cell manipulation is performed by the use of two-dimensional optical tweezers system generated by dual axis acousto-optical deflectors. In the second setup, trapping configuration is extended to three-dimensional volumes using DOEs.
