Luminescent Saccharide Biosensor by Using Lanthanide-Bound Lectin Labeled with Fluorescein

摘要

In biosensing,it is considered that metal-based luminescence has advantages over fluorescence on several points,such as the unique longer lifetime of emission,a lower scattering of excited light,the lack of disturbance with fluorescent impurities,and the absence of analogues properties in the biological sample.Thanks to these benefits,a luminescence mode sensing system is anticipated to be promising particularly for application to complicated mixtures of biological samples.Unfortunately,the high sensitivity of luminescence to dissolved oxygen frequently prevents precise and reproductive luminescent analysis.
