文摘

This paper developed a new fluorescent rhodamine-based derivatives (RAD) probe for highly sensitive and selective detection of Cu²⁺ and L-Methionine (L-Met). The detection limits can reach as low as 12 nM for Cu²⁺ and 5 nM for L-Met, In addition, the RAD probe can be further applied to cell imaging owing to its photostability and low cytotoxicity.
