Mahsa Nasehi presented our latest work at SPIE Photonics Europe in Strasbourg (Paper 14076-20), titled “Development of functionalized gold nanoparticles with dual optical properties for biomedical imaging.” The work focuses on the development of gold nanoparticles that combine plasmonic and photoluminescent properties in a single system without additional surface modification. The particles show uniform morphology, good colloidal stability, and favorable biocompatibility. Their intrinsic optical properties enable both fluorescence and surface-enhanced Raman scattering (SERS), supporting their use as label-free probes for biomedical imaging. The presented synthesis approach is straightforward and scalable, providing a platform for multifunctional nanomaterials in diagnostics and optical sensing.
