Figure Lengend Snippet: Photothermal conversion analysis using novel contact‐mode NIR laser irradiation via GI‐POF rigid endoscope. (a) Schematic diagram of the graded‐index plastic optical fiber (GI‐POF) rigid endoscope system architecture. The output power at the tip of the GI‐POF rigid endoscope was set to 300 or 500 mW, corresponding to power densities of approximately 91 and 152 W cm −2 , respectively, based on a laser emission area of 0.33 mm 2 . (b) Illustration demonstrating minimally invasive contact‐mode laser irradiation to tumor‐bearing mice. (c) Experimental setup for photothermal conversion measurement in solution. (d) Concentration‐dependent photothermal heating of IDP1‐CNH/ICG suspension. Temperature increase (Δ T ) was measured at CNH/ICG concentrations ranging from 1 to 100 μg mL −1 under constant 300 mW laser irradiation for 5 min. Data are presented as mean ± SD ( n = 3). (e) Laser power‐dependent photothermal heating at a fixed IDP1‐CNH/ICG concentration (10 μg mL −1 ). Data are presented as mean ± SD ( n = 3). (f) Thermographic images visualizing spatial temperature distribution during contact‐mode laser irradiation. IDP1‐CNH/ICG suspension (10 μg mL −1 , top row) and 50 μg mL −1 (bottom row) were irradiated at 500 mW. (g) Direct comparison of contact‐mode versus noncontact‐mode laser irradiation efficiency. IDP1‐CNH/ICG suspension (10 μg mL −1 ) and PBS control were irradiated at 500 mW for 5 min using either contact‐mode (GI‐POF rigid endoscope insertion with power intensity ∼152 W cm −2 ) or noncontact‐mode (external 808 nm laser positioned ∼1 cm above solution surface). Data are presented as mean ± SD ( n = 3). Power intensity at the fiber tip was calculated as 500 mW/0.33 mm 2 = 152 W cm −2 based on a laser emission area of 0.33 mm 2 at the endoscope tip. (h) Photothermal stability and recyclability assessment. IDP1‐CNH/ICG suspension (50 μg mL −1 ) was subjected to five repeated heating–cooling cycles (500 mW, 5 min heating followed by natural cooling to room temperature). (i) UV–vis‐NIR absorbance spectra of IDP1‐CNH/ICG before (pre‐irradiation, blue line) and after (post‐irradiation, red line) laser irradiation (500 mW, 5 min).
