摘要

We demonstrate a glucose fiber sensor for measuring glucose concentration in serum.High resolution and rapid measurement are achieved through the integration of highly selective enzymes and heterodyne interferometry.The best resolution and response time obtained are 0.14 mg/dL and 1.3 s,respectively.The stability of the sensor is also verified by investigating the initial phase variation.Experimental results show that the fiber sensor can be reused more than 10 times.Fiber sensors have attracted considerable attention over the past two decades.Various kinds of fiber sensors have been proposed for measnring specific chemical concentrations[1-8].Most previously reported methods[1-5] involved measuring the variations in fluorescence intensity[2-4] or transmitted light[3,4].Hence,avoiding the inflnence of snrrounding light and the use of expensive photon detection equipment are important requirements.Furthermore,procedures for manufacturing optical biosensors are complicated[3] and qualitv is difficult to control[4]..
