Therefore, site-selective effective phase engineering is crucial for the fabrication of MoS<inf>2</inf>-based photoelectrochemical devices. Here, we employed a flash phase engineering (FPE) strategy to precisely fabricate a 2H-1T heterophase structure. This technique allows simple, efficient, and precise control over the micropatterning of MoS<inf>2</inf> nanofilms while enabling site-selective phase transition from the 1T to the 2H phase. The detection of reduced glutathione (GSH) showed an approximately 5-fold increase in sensitivity when using the electrode fabricated by FPE.en2046-20692024747304733Technology::600: TechnologyJournal Article10.1039/d3ra07759dJournal Article
