  1. Nature of Single-Walled Carbon Nanotubes' Interactions with Differing Photosensitizers

    31 Aug 2023 | | Contributor(s):: Rubiona Grainger, Nima Soltani, Rice University

    It was recently discovered that when Single-Walled Carbon Nanotubes (SWCNTs) wrapped with single-stranded DNA are exposed to singlet oxygen the singlet oxygen reacts with the guanine nucleotides embedded in the DNA. The singlet oxygen is produced by irradiation of a photosensitizer. However,...
