Abstract:
In this study, a novel dual-function probe BMP based on benzothiazole was easily synthesized and characterized through common optical technique. In the system consisting of DMF/H2O (v/v, 2/3), probe BMP showed azure and blue-green to Al3+ and Ga3+, respectively. Besides, the binding ratios of BMP to Al3+ and Ga3+ were determined as 1:1, which confirmed by Job's plot. Furthermore, for Al3+ and Ga3+, the limit of detection (LOD) was determined to be 1.51 × 10-6 M and 4.28 × 10-6 M, respectively. Moreover, it was worth noting that BMP showed good performances in paper colorimetry, cell phone colorimetric identification and cell imaging.

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
