Disclosed are methods and apparatuses for identifying and sorting cells based on the cells' response to an external stimulus. Cellular adherence to liquid crystals with tunable wettability is measured before and after an induced change in the liquid crystal wettability. The cell-based liquid crystal reorientation can be measured and used for monitoring and sorting of cells in a label-free manner, and thus provides a positive method for selecting cells, such as stem cells, for use in tissue engineering applications.
