“…2-D PC structures are ordered lattices, which can be created by a regular row of holes, wires, rods, and tubes. 87,88 Their unique characters such as photon localization make them rapidly evolve in the field of physics, chemistry, biology, materials science, nanotechnology, etc. [89][90][91][92] Compared with 1-D and 3-D PC sensors, 2-D PC sensors required a small amount of different materials and a thin overall structure, result in excellent sensitivity and response.…”
