Near‐Infrared Photochemistry Harnesses Excitons for Selective Guanine Functionalization of Single‐Wall Carbon Nanotubes
Researchers have demonstrated that semiconducting single‑wall carbon nanotubes (SWCNTs) can act as their own photosensitizer under near‑infrared (NIR) illumination, producing singlet oxygen that selectively oxidizes guanine bases in the surrounding ssDNA corona.

This self‑sensitized approach enables selective modification of targeted SWCNT structures in mixed samples.
