Lanthanide/nucleotide coordination polymers: an excellent host platform for encapsulating enzymes and fluorescent nanoparticles to enhance ratiometric sensing

fluorescence and specific recognition of hydrogen peroxide, a dual-emissive GOx&CDs@AMP/Tb-CPBA composite was further fabricated for the ratiometric sensing of glucose. Benefiting from the synergistic effect of GOx and CDs in the highly efficient transfer of intermediates and the elimination of environmental fluctuations, the presented ratiometric sensor not only displayed an ultrahigh sensitivity with a detection limit of 80 nM, but also allowed glucose to be easily identified by the naked eye under a UV lamp. We hope that this study will provide a new insight into the design and application of coordination polymer-based multifunctional composites.
