Recently, the application of photonic crystals was considered for recognizing chemical and biochemical molecules. A photonic crystal is a periodic dielectric structure, and it is categorized into one dimension, two dimensions, and three dimensions. The photonic band gap is the significant parameter in a photonic crystal. The photonic band gap manages the forbidden frequency and range of wavelength in the photonic crystal. Therefore, the response of photonic crystal can be adjusted using a photonic band gap and can be designed to detect biomolecules and chemical molecules. In this chapter, the various type of photonic crystals structure and the mechanism of a photonic crystal for biosensors have been considered for the detection and monitoring of biomolecules and biotargets, including nucleic acid (DNA or RNA) proteins, and cancer cells.
