Abstract

The detection of glucose level in human body is very necessary for motoring physical condition. In our work, a triple tapered sensor probe based localized surface plasmon resonance (LSPR) is developed to detect various glucose concentration solution. The single-mode fiber (SMF) is utilized to prepare the proposed triple tapered structure. The serial taper structure in the sensing area insure more evanescent wave (EW) leak out. Gold nanoparticles (AuNPs) are modified on the serial triple tapered fiber (STTF) structure to stimulate the LSPR phenomenon. The limit of detection (LOD) and sensitivity of sensor are 3.8 mM and 0.59 nm/mM, respectively. Moreover, the reproducibility, selectivity, pH test, and reusability of STTF probe are evaluated to validate the ability in practice.
