Abstract


This presentation will review our on-going research activities on laser ablative synthesis of colloidal plasmonic (Au, Ag) nanomaterials. Our approach is based on the employment of ultra-short laser radiation to ablate a solid target or colloidal micro/nano particulates in biocompatible aqueous solutions and thus form functional colloidal nanoparticles of variable size and low size dispersion. The surface of nanoparticles can be functionalized by the addition of proper chemicals (biopolymers etc) during ablation process. Exhibiting exceptional purity and exempt of any residual contamination, the nanomaterials present unique structures for biological imaging and therapy, as well as for SERS-based sensing
