The HPLC method also further confirmed that shows good practical application prospects. Moreover, the optimum was remarkably sensitive and selective in detecting DA among various analogs and showed good anti-interference ability. The developed ratiometric fluorescence sensor showed an obvious and meaningful color change with a gradual increase in DA concentration under a UV lamp. In the presence of DA, the fluorescence intensity of the optimum was remarkably quenched by DA, achieving a linear range of 0–600 nM and a limit of detection of 12.35 nM. The program structure is a free software package for using multi-locus genotype data to investigate population structure. The TEM image demonstrated that the sensor was a hollow structure, which could have ample opportunity to excite quantum dots to emit light through multiple light scattering through holes.

CdTe QDs and CDs were used as the reference signal and recognition signal, respectively, and thus showed a visual effect. A ratiometric hollow sensor was developed for the sensitive and selective detection of dopamine (DA). Developing hollow-structure quantum dot carriers to increase quantum luminous efficiency is a creative idea for designing a novel sensor.
