    • Nanoparticle transducers and methods of use thereof for the detection of analyte concentrations in a fluid are provided. Nanoparticle transducers can comprise a nanoparticle, such as a Pdot, coupled to an enzyme that catalyzes a reaction with the analyte. The nanoparticle transducers further comprise chromophores that emit fluorescence that varies as a function of the concentration of one of the elements of the reaction. The nanoparticle transducer thus changes fluorescence as the analyte concentration changes, transforming analyte concentration values into fluorescence intensities. The measurement of these intensities provides a measurement of the analyte concentration. The nanoparticle transducers are biocompatible, allowing for use in vivo, for the monitoring of analyte blood concentrations such as blood glucose concentrations.
    • 提供纳米粒子换能器及其用于检测流体中分析物浓度的使用方法。 纳米颗粒换能器可以包含与催化与分析物反应的酶偶联的纳米颗粒,例如P点。 纳米颗粒换能器还包含发射荧光的发色团,所述荧光根据反应的元素之一的浓度而变化。 纳米颗粒换能器因此在分析物浓度改变时改变荧光,将分析物浓度值转化为荧光强度。 这些强度的测量提供了分析物浓度的测量。 纳米粒子换能器是生物相容的,允许在体内使用,用于监测分析物血浓度,例如血糖浓度。
