Abstract

•Novel DSCM has been fabricated via a one-step strategy for the first time.•A possible formation mechanism of DSCM has been briefly discussed.•DSCM showed excellent performance and super sensitivity as SERS substrate.

Based on a facile, environment-friendly, simple one-step method in aqueous solution, a novel dumbbell-like silver citrate (Ag3C6H5O7, SC) microstructure (DSCM) was successfully synthesized for the first time. The DSCM was confirmed by SEM, and further structurally characterized by XRD. A possible formation mechanism of DSCM has been briefly discussed based on the morphology evolution of SC microstructures at different growth stages. Moreover, surface enhanced Raman scattering characterization revealed significantly higher Raman signal for the absorbed 2-mercaptopyridine (2-MPY) molecule and super sensitivity by using the as-fabricated DSCM substrate.

Graphical abstractBased on a facile, environment-friendly, simple one-step strategy method in aqueous solution, a novel dumbbell-like silver citrate (Ag3C6H5O7, SC) microstructure (DSCM) was successfully synthesized for the first time. The SERS results reveal that the prepared DSCM showed excellent performance and super sensitivity as SERS substrate with 2-MPY molecule as a SERS reporter.Figure optionsDownload full-size imageDownload as PowerPoint slide
