研究目的
Investigating the fabrication and performance of Ag nanoparticle decorated MnO2 flakes as flexible SERS substrates for the detection of rhodamine 6G (R6G).
研究成果
The AgNPs/MnO2@Al flexible substrates demonstrated superior SERS performance for R6G detection, attributed to the porous structure of MnO2 nanoflakes that facilitate Ag nanoparticle immobilization. The study highlights the importance of substrate morphology in SERS applications and suggests potential for further development of flexible SERS substrates.
研究不足
The study is limited by the dependency of SERS performance on the morphology of the MnO2@Al substrate, which may require precise control over synthesis conditions. Potential areas for optimization include the uniformity of Ag nanoparticle distribution and the scalability of the substrate fabrication process.
