Low Detection Limit

We present a recyclable SERS-based immunoassay for CA19-9 with a low detection limit of 5 U mL−1. The linking between TiO2-NTs and 4MBA was destroyed by catalyzing 4MBA into 4-sulfobenzoate upon UV irradiation, which was clarified by UPLC/ESI-tqMS and density functional theory.
