Ti3C2Tx-AgNPs@beta-cyclodextrin SERS substrate for rapid and selective determination of erythrosin B in dyed food

In this work, a native beta-cyclodextrin capped silver nanoparticles decorated Ti3C2Tx nanosheets (Ti3C2Tx[email protected]β-CD) surface-enhanced Raman scattering (SERS) substrate was developed by a facile one-pot method. The two-dimensional Ti3C2Tx nanosheets not only acted as the supporter to load AgNPs, but also served as chemical enhancement material. Meanwhile, β-CD played a critical role in the control of morphology and size of AgNPs, and...
