Microfiber-based sensor for measuring uric acid concentrations

Microfiber sensor is proposed and demonstrated using a fiber optic displacement sensor (FODS) based on intensity modulation technique for measurement of different concentrations of uric acid. The proposed sensor uses singlemode fiber (SMF) tapered using flame brushing technique to enhance the e...
