Fabrication of branched gold copper nanoalloy doped mesoporous graphitic carbon nitride hybrid membrane for surface-enhanced Raman spectroscopy analysis of carcinogens

Recent Progress on Solid Substrates for Surface-Enhanced Raman Spectroscopy Analysis

“…The noble metals doped semiconductor composite is an ideal SERS substrate due to the synergistic effect of localized surface plasmon resonance (LSPR) properties of noble metals and charge transfer of semiconductor. Our group [ 45 ] have developed a branched AuCu nanoalloy doped mesoporous graphitic carbon nitride hybrid hydrophobic membrane (mpg-C 3 N 4 /AuCu) for sensitive and selective analysis carcinogens including benzidine and zearalenone in food samples ( Figure 2 b). The high sensitivity was based on the design strategies of the anisotropic structure of AuCu, mesoporous semiconductor of mpg-C 3 N 4 , and hydrophobicity.…”

3D Hot Spots Droplets on the MoS2/Al Hydrophobic Array Interface for SERS Quantitative and Multiplex Detection of Pesticide Residues

“…Surface-enhanced Raman spectroscopy (SERS), a promising analytical technology due to its high sensitivity, simple pretreatment, fast and nondestructive analysis, as well as fingerprint features, thus it has been widely applied in ultrasensitive molecular detection fields such as food safety, [1,2] environmental monitoring, [3,4] biotechnology, [5,6] catalysis process, [7,8] etc. The SERS signal amplification is generally originated from the giant electromagnetic enhancement (EM) caused by capability of SERS.…”
