Herein, we investigated the correlation between curcumin and glutathione (GSH) levels in mammalian cells using gold nanoparticles (AuNPs) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). GSH exists in high concentration in the cytosol and acts as a major
