Two-dimensional Photonic Crystal Sensor for Detection of Biomaterial

Biological components includingcells, proteins,and nucleic acids have beenstudied by usingbiological sensors. All compounds in the organisms have sensors with identical mechanical sensors. Most of these sensors are specific cells which are sensitive to physical characteristics of outside environmentincluding light, motion, temperature, magnetic-field, gravity, moisture, vibration, pressure, electrical fields,andsound. Since biosensors couldbe fabricated by using photonic crystals, these structures areused in designing the sensor due to the unique characteristics of photonic crystals. Refractive index around the sensing hole was changed and output transmission spectrum was studied. By changing refractive index, transmission spectrum undergoes measurable change and biomolecule couldbe measured by sensor in mentionedconditions.Results have shown that this sensor has good sensitivity for measuringsmall dimensions. In addition, high speed, high quality, simple structure, as well as higher sensitivity are other characteristics of photonic crystal sensors compared to other sensors.
