Abstract:
We report herein a strategy involving using a single fluorescent probe with the assistance of two pH conditions to simultaneously detect cysteine and homocysteine quantitatively. The concentrations of Cys and Hcy in human serum samples were found to display a positive correlation, which might promote a further understanding of thiol-related diseases.
