Abstract
Diabetes mellitus is a disease of metabolic disorders where human blood contains a high amount of sugar level for a prolonged period. This study aims to simulate the effectiveness of sensors based on microring resonator (MRR) and surface plasmon resonance (SPR) for diabetes monitoring. The results show that a sensor based on MRR and SPR provides the ability to detect low levels of glucose concentration as low as 7 mM (0.13%) and the ability to detect resonance shift for very small glucose concentration change. Therefore, the sensor based on MRR and SPR can be used for diabetes monitoring. The sensitivity of the sensor based on MRR and SPR is 85.84 nm/RIU and 116.69°/RIU, respectively. These findings are important for the development of diabetes monitoring based on MRR or SPR.
