Photothermal Transport for Guiding Nanoparticles Through the Vitreous Humor

Advanced Science, EarlyView.
Nanosecond laser irradiation of the clinically approved dye indocyanine green (ICG) enables light‐guided nanoparticle transport within the vitreous humor. The combined use of ICG and pulsed laser illumination induces localized convection and thermophoresis, directing particles toward illuminated regions.
