Cisplatin (CIS) and etoposide (ETP) combination therapy is highly effective for treating various cancers. However, the potential pharmacokinetic interactions between these drugs necessitates selective sensing methods to quantitate both CIS ETP levels in patient's plasma. This work develops a dual fluorescence probe strategy using glutathione-capped copper nanoclusters (GSH-CuNCs) nitrogen-doped carbon dots (N-CDs) simultaneous analysis of ETP. The signal GSH-CuNCs at 615 nm increased...
