A Water-Soluble Polymer for Selective Colorimetric Sensing of Cysteine and Homocysteine with Temperature-Tunable Sensitivity |
| 초록 |
We emphasize the synthesis and development of an aldehyde-functionalized azo-containing thermoresponsive polymer for colorimetric sensing of cysteine and homocysteine. Water-soluble polymeric probe for selective sensing of cysteine and homocysteine by colorimetric titration was designed and synthesized. Most interestingly, temperature-tunable sensitivity of cysteine detection was achieved. The polymer selectivity toward various amino acids was investigated, and the highest selectivity (25-30-fold higher) was achieved for cysteine and homocysteine compared to other amino acids. The temperature-dependent cysteine sensing studies were performed to demonstrate temperature-tunable sensitivity towards cysteine. The sensing ability decreased with increasing temperature from 25 to 55 oC due to hydrophobic aldehyde moieties being hidden in the folded chains of the polymer. |
