Red‐Emissive Carbon Dots for Fluorescent, Photoacoustic, and Thermal Theranostics in Living Mice

Novel red-emissive carbon-dots (C-dots) with broad absorption in the region from 400 to 750 nm are prepared from polythiophene phenylpropionic acid. Upon near infrared laser irradiation, the red-emissive C-dots show strong photoacoustic response and high photothermal conversion efficiency (η ≈ 38.5%). These unique properties enable the C-dots to act as multifunctional fluorescent, photoacoustic, and thermal theranostics for simultaneous diagnosis and therapy of cancer.
