The "fiber-cell" biosensor system is mainly composed of the following three parts: (1) A multi-core optical fiber with a novel structure, its fiber end is polished into a non-equilateral pyramidal shape and prepared into optical tweezers; (2) Microspherical optical resonant cavity, the gain medium with amplification function in the cavity can be distributed in the sphere, outside the sphere or the surface of the sphere shell. The microsphere can be an oil drop injected into the cell, or it can be engulfed by the cell to the internal microspheres; (3) Living single cells to be tested placed in liquid.~- .~I I I I ui ' . ! ;CC_
