Advantages

Generates ROS via plasmon-driven catalysis and Mn-mediated Fenton-like reactions under 1064 nm laser irradiation

Mild hyperthermia promotes oxygenation and disrupts DNA repair pathways, leading to multi-directional DNA damage and increased immunogenic cell death (ICD)

Released Mn²⁺ activates the cGAS-STING pathway, synergizing with ICD to promote systemic antitumor immunity
