Highly Sensitive Bilirubin Biosensor Based on Photonic Crystal Fiber in Terahertz Region

Abstract: An unstable bilirubin level in the human blood causes many dangerous health problems, such as jaundice, coronary artery disease, ulcerative colitis, and brain lesions. Therefore, the accurate and early detection of bilirubin concentrations in the blood is mandatory. In this work, a highly sensitive biosensor based on photonic crystal fiber (PCF) for monitoring bilirubin levels is proposed and analyzed. The sensor parameters, including relative sensitivity, effective mode area, confinement loss, and effective m… Show more

“…Terahertz (THz) spectroscopy has shown great potential as a label-free, non-contact, and non-destructive technique for sensing chemical and biological substances [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Metamaterials operating in the THz range are particularly useful for detecting biological substances, including microorganisms and viruses [20][21][22][23][24][25][26][27][28][29][30][31][32].…”
