A plasmonic AgNP decorated heterostructure substrate for synergetic surface-enhanced Raman scattering identification and quantification of pesticide residues in real samples

Abstract

Rapid and on-site Raman spectroscopic identification and quantification of pesticide residues have been restricted to the low instrumental sensitivity of the portable Raman instrument, no ideal platforms have been reported...

Sensitive determination of thiram in apple samples using a ZIF-67 modified Si/Au@Ag composite as a SERS substrate

“…Several types of MOF-based SERS substrates have been developed to analyze pesticide molecules. [26][27][28] For example, Xuan et al 23 fabricated a SERS substrate via in situ reduction of silver and gold nanoparticles on inositol hexaphosphate (IP 6 )-functionalized Mil-101(Fe), which exhibited sensitive Raman detection of trace thiabendazole in juice samples. A facile method to construct SERS substrates composed of 2D Ni-MOF nanosheets with core-shell Au@Ag nanoparticles was developed by Lai et al 27 and the detection limit of thiram can be as low as 87.1 mg L −1 .…”
