Surface-enhanced Raman spectroscopy (SERS), a highly sensitive non-destructive analytical technique, has recently emerged as a probing tool in medical diagnostics, forensics, quality control, and food safety. The plasmonic ink approach is a well-known technique that enables the on-demand deposition oftailorable-morphology SERS-active coatings by extruding colloidal suspensions of SERS-active nanoparticles ("plasmonic inks") via micro-dispensers [1]. Currently, the study of plasmonic inks is focused on SERS-active noble-metal nanoparticles (NPs), such as silver [2], gold [3], gold-silver alloy NPs [4].
Hybrid SERS platforms comprised of noble-metal and layered-material phases, such as MXenes and transition metal dichalcogenides (TMDCs) have recently emerged as promising SERS-active media. For example, in recent study [5], it was demonstrated that Au@MoS2@Au core-shell NPs combine the electromagnetic field SERS enhancement from gold component and chemical SERS enhancement from TMDC.
In the current study, we investigate various plasmonic inks obtained by robust and tunable method of pulsed laser ablation in liquids. We demonstrate that structure of hybrid NPs, optical absorbance and SERS performance of resulting inks significantly depend on the ratio of layered and noble-metal components. The obtained results will pave the way to the development of highly reproducible analyte-selective plasmonic inks.
