In this paper, we designed a small-size biosensor to detect the DNA molecules using a 2D hexagonal photonic crystal without any change in the radius of the holes. The sensing mechanism is based on the change in the refractive index of sensing holes and the intensity variation of the output transmission spectrum. By infiltrating the analyte within the sensing holes for one unit change in the refractive index, the normalized intensity of the transmission spectrum is reduced to 4 units. To analyze the performance of this structure, we used the plane wave expansion and the finite difference time domain methods. The regression coefficient is equal to -0.9689..
