高灵敏度振荡场生物传感器的理论与实验研究
Theoretical and experimental investigation on high sensitivity oscillating field biosensor
摘要
Abstract
A novel oscillating field biosensor was proposed utilizing ultrahigh-order modes excitated in a symmetrical metal cladding waveguide (SMCW). Different from the conventional biosensors, such as surface plasmon resonance sensor (SPRS), leaky mode waveguide sensor (LWS) and reverse symmetry waveguide sensor (RSWS), the sample is placed inside the guiding layer. Since the guiding layer supports a high intensity oscillating field, the intensity of output light is rather sensitive to the tiny variation of refractive index, which leads to very high sensitivity and resolution. Based on the noise level, lppm variation of the glucose solution was detected in the experiment. The proposed scheme is expected to have a wide application and promising future in various biomedical detections.关键词
