A Surgical Dye Holds Its Glow Four Times Longer
Polymerizing indocyanine green shielded its light-emitting structure and slowed photobleaching in laboratory and mouse tests.
Summary
Polymerizing indocyanine green shielded its light-emitting structure and slowed photobleaching in laboratory and mouse tests.
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.
Why it matters
Polymerizing indocyanine green shielded its light-emitting structure and slowed photobleaching in laboratory and mouse tests.
Limits and context
- Cell, spheroid, and mouse experiments supported further study for image-guided surgery, but the new polymer is not yet an approved clinical dye.
