In biosensors, the investigated material is biological components such as cells, proteins, and nucleic acids. All compounds of living organisms have sensors with functions similar to mechanical sensors. Most of these sensors are special cells sensitive to the external environment's physical characteristics such as light, movement, temperature, magnetic field, gravity, humidity, vibration, pressure, electric fields, sound, etc. Biosensors can be made using photonic crystals, an example of which is designed here. In order to check the biomolecule detection ability by the biosensor, the refractive index around the sensing hole is changed and the output transmission spectrum is limited. By changing the refractive index, the transmission spectrum can be measured, which enables the sensor to identify biological molecules. In this study, a sensor was designed that is capable of detecting biological molecules. This sensor has good sensitivity, which makes it capable of measuring in a small size. The sensor can accurately predict the result, so this sensor is very suitable for medical purposes.
