Three-dimensional ordered macroporous nano-architecture and its enhancing effects on Raman detection sensitivity for Eosin Y molecules

In this work, three-dimensional ordered macroporous (3DOM) TiO2 was delicately designed and synthesized via template method. Ag nano-particles (NPs) were assembled inside the 3DOM TiO2 network to form 3DOM-TiO2@Ag composite nano-architecture. Raman signal of EY were effectively amplified by such designed 3DOM-TiO2@Ag nano-architecture due to the intrinsic advantages and synergistic effect of each components in it.309
