The HPLC method also further confirmed that has a good practical application prospect. Moreover, the optimum was remarkedly could sensitive and selective detecting DA in various analogs and anti-interferences. The developed ratiometric fluorescence sensor showed an obvious color change with a gradual increase in DA concentration, which was observed by the naked-eye under UV lamp. In the presence of DA, the fluorescence intensity of optimum was remarkedly quenched by DA, achieving a linear rang of 0-600 nM and a limit of detection of 12.35 nM. TEM image demonstrated that the sensor was a hollow structure, which could get ample opportunity to excite quantum dots to emit light through multiple light scattering through holes. MIPs provided a highly selective toward DA. The CdTe QDs and CDs were reference signal and recognition signal, respectively, thus it has a visual effect.

A ratiometric hollow sensor was developed for sensitive and selective detection of dopamine (DA). Developing hollow-structure quantum dots carriers to increase quantum luminous efficiency was a creative idea for designing novel sensor. Using polysulfide electrocatalysts has become an effective strategy to improve the durability of lithiumsulfur batteries (LSBs) by regulating the precipitation and dissolution of lithium sulfide in the electrolyte.
