ABSTRACT:
A laser manipulation apparatus for trapping and separating an optional micro-sample comprising a cell plate having a first cell for storing a liquid medium containing micro-sample s and a second cell for storing a liquid medium not containing micro-sample s each of the first and second cells being opened at the upper surface, in communication with each other by way of a narrow induction channel for inhibiting free movement of the micro-sample s, an optical trapping system for irradiating and trapping a single micro-sample out of a group of micro-sample s dispersed and suspended in the liquid medium stored in the first cell and a sample separation device for moving the single micro-sample from the first cell through the induction channel into the second cell.
