Laser Ablation in Liquids as a Versatile Approach for the Synthesis of Hybrid Nanoparticles with Plasmonic and Magneto-Plasmonic SERS Applications. In: SBFoton International Optics and Photonics Conference (SBFoton IOPC), Setembro 21-24, 2025, São Pedro, SP. Piscataway, Nova Jersey: IEEE, 2025.

Disponível em: https://repositorio.ipen.br/handle/123456789/49378.https://repositorio.ipen.br/handle/123456789/49378The synthesis of nanomaterials with tunable optical and magnetic properties is essential for applications in nanomedicine, sensing, and bioimaging. This work explores Laser Ablation in Liquid (LASiS) as a clean and efficient method for producing hybrid nanoparticles for use as SERS (Surface-Enhanced Raman Spectroscopy) substrates. We synthesize and characterize two types of hybrid nanoparticles: metallic Au-Ag alloys and core-shell Au-Fe(oxide) structures. The study demonstrates how LASiS enables the engineering of nanomaterials with enhanced properties for electric field amplification in vibrational spectroscopy, highlighting its potential as a versatile tool for nanobiophotonics applications through a unified experimental approach.engopenAccessTexto completo de evento10.1109/SBFOTONIOPC66433.2025.11218607
