We synthesize monodispersed, fluorescent gold nanoparticles with gallic acid based ligand shells at an average size of 5nm. Due to their small size and characteristic surface plasmon resonance (SPR) they are suitable for biomedical applications. Our research focuses on exposing CHL-1 cells, a cell line derived from human melanoma cells, infused with those gold nanoparticles to photothermal treatment near the peak SPR at 532nm. After treatment, cells are incubated and submitted to two types of analysis (MTT assay and Crystal Violet Staining) to evaluate cell viability. We present results on how the photothermal treatment over various time intervals affects the cell viability.
