High sensitivity biological sample measurement has been achieved by using a 10° tilted fiber Bragg grating. Human acute leukemia cells with different intracellular densities were clearly discriminated by identifying their slight refraction index (RI) perturbations in the range from 1.3342 to 1.3344, combining with a temperature self-calibration property.
