Description
 
This technology can harvest the cells of interest directly or can isolate specific cells by cutting away unwanted cells to give histologically pure enriched cell populations. A laser is coupled into a microscope and focuses onto the tissue on the slide. By movement of the laser by optics or the stage the focus follows a trajectory which is predefined by the user. This trajectory is then cut out and separated from the adjacent tissue. After the cutting process, an extraction process has to follow if an extraction process is desired. Ultraviolet pulsed lasers (355 nm) are commonly used for the cutting of the tissues and sometimes in combination with an IR laser responsible for heating/melting a sticky polymer for cellular adhesion and isolation.
