1. A method of identifying a state of a cell, the method comprising:
- culturing the cell on an area of the surface of a resonant wave guide grating (RWG) biosensor in a label free optical biosensor system including a light source, and a label independent detector, to form a cell-biosensor composition; and
assaying the cell-biosensor composition, where the assaying comprises identifying the inhomogeneity of the state of the cell at the area of the surface of the RWG label-free optical biosensor where the cell is cultured.
