Figure Lengend Snippet: a Photograph showing the stented (AuNP-integrated silicone-covered SEMS) esophagus (arrow) during NIR laser irradiation. b Photothermal image showing the stented (AuNP-integrated silicone-covered SEMS) esophagus (cursor) during NIR laser irradiation. AuNP , Gold nanoparticle; NIR , Near-infrared; SEMS , Self-expandable metal stent

Article Snippet: The sheath was then withdrawn from the stented esophagus, leaving the optic fiber in place, and 808 nm NIR laser irradiation (Lumen Photonics, Beijing, China) was performed at a power output of 1.6 W for 2 min (Fig. b,c).

Techniques: Irradiation
