Dual channel detection of GSH based on AgNTs colorimetry and coupled plasmonic SERS.
Glutathione (GSH) is a crucial intracellular antioxidant that plays a central role in redox homeostasis, and its abnormal levels are closely associated with the pathogenesis of various diseases. Consequently, the development of rapid, sensitive, and reliable biosensing strategies for GSH quantification is of significan...
