Facile synthesis of plasmonic BP@Au nanomatrix for sensitive detection of irinotecan and its active SN-38 metabolite via laser desorption/ionization mass spectrometry.

A new methodology is presented for the rapid, specific, and sensitive detection of irinotecan (CPT-11), a chemotherapeutic agent utilized in the treatment of cancer, along with its metabolically active derivative, SN-38, via laser desorption/ionization mass spectrometry (LDI MS). The method includes the detection of camptothecin (CPT), which can be utilized as an internal standard for the quantitative assessment of both CPT-11 and SN-38 in mouse serum. The approach utilizes a plasmonic two-dimensional (2D) black phosphorus nanosheet (BPN)-gold nanomatrix (BP@Au) in LDI MS.
