Combined Photothermal and Chemotherapy to Induce Cancer Cell Damage in Spheroids Using Gold Nanostars and Gold Nanorods

Particle &Particle Systems Characterization, Volume 43, Issue 4, April 2026.
Gold nanostars are prepared in a 1‐min synthesis process to reach a plasmonic resonance in the near infrared. Upon laser excitation, they show mild hyperthermia, like gold nanorods with similar plasmonic properties. Spheroids are selected to mimic solid tumors in vitro.
