摘　　要：Glucose is an indispensable nutrient for metabolism in living organisms and is widely used in food,industry,and medical fields.Glucose is often added as a sweetener in food and often used in industry as a reducing agent for various products.In medical treatment,glucose is added to many drugs as a nutritional additive,and it is also an indicator that diabetics need to pay attention to at all time.Therefore,the market has a great demand for low-cost,high-sensitivity,fast,and convenient glucose sensors,and the industry has always attached great importance to the work of creating new glucose sensor devices.Therefore,we proposed a SnO_(2)nanofibers/Au structure multimode-single-mode-multimode(MSM)fiber surface plasmon resonance(SPR)glucose sensor.SnO_(2)nanofibers were fixed to a single-mode fiber core that had been plated with the Au film by electrospinning.When the glucose concentration increased at 5 vol%intervals,the corresponding resonance wavelengths had different degrees of redshifts.Comparing the two structures,as the glucose concentration range increased from 0 vol%to 60 vol%,the sensitivity increased from 228.7 nm/vol%in the Au structure to 337.3 nm/vol%in the SnO_(2)nanofiber/Au structure.At the same time,the linear correlation between the resonant wavelength and the refractive index of the two structures was greater than 0.98.Moreover,the SnO_(2)nanofibers/Au structure significantly improved the practical application performance of SPR sensors.
