Heterojunction-engineered two-dimensional Ti 3 C 2 -CoFe 2 O 4 nanozyme with oxidase-like activity for SERS detection of glutathione in human serum

Key Points

• This research aims to enhance the detection of glutathione in human serum using a novel nanozyme.
• Engineered a heterojunction nanozyme combining Ti3C2 and CoFe2O4.
• Evaluated oxidase-like activity of the nanozyme in a controlled environment.
• Applied surface-enhanced Raman scattering (SERS) techniques to detect glutathione.
• Demonstrated strong enhancement of Raman signals for glutathione detection.
• Achieved improved sensitivity compared to conventional methods.
• Showed effective detection in human serum with minimal background interference.
