Copper contamination in water and irrigation sources is an essential environmental exposure pathway that can affect ecosystem health and, indirectly, food safety. Here, we present a sustainable optical sensing platform based on bio-inspired carbon quantum dots (CQDs) synthesized from Mucuna pruriens seeds via a green hydrothermal route. The synthesis yields uniformly dispersed nanoparticles (~2.5 nm) enriched with oxygen- and nitrogen-containing surface functionalities, imparting strong colloidal stability and efficient photoluminescence with a quantum yield of 18.70%. These CQDs exhibit excitation-dependent fluorescence that is selectively quenched by Cu2+ ions via a photoinduced electron transfer (PeT) mechanism, achieving detection limits of 0.34 μM. The CQDs enable both solution-based and filter paper-mediated visual detection. Low phytotoxicity in seed germination assays underscores their environmental compatibility. This study demonstrates that Mucuna pruriens-derived CQDs provide a promising, sustainable fluorescent agent for sensitive, portable monitoring of Cu2+ ions in aqueous environments.
