    "body_text": "Korea Research Institute of Chemical Technology researchers linked molecules of the approved near-infrared dye indocyanine green into a polymer backbone. Under continuous 785-nanometer illumination, conventional dye fell to about 40% intensity within 50 seconds; KR-NIR-P retained about 66% after 200 seconds. Cell, spheroid, and mouse experiments supported further study for image-guided surgery, but the new polymer is not yet an approved clinical dye.",
