A high-performance Au@γ-Al2O3 SERS substrate for reliable monitoring of trimethoprim.
Novel Au@γ-Al2O3 nanoparticles were synthesized and used as a substrate for the determination of trimethoprim (TPM) in samples by surface-enhanced Raman spectroscopy (SERS). The newly prepared Au@γ-Al2O3 nanoparticles were characterized by ultraviolet spectroscopy, infrared spectroscopy and scanning electron microscopy...
