Ultra-Low Doses of Chirality Sorted (6,5) Carbon Nanotubes for Simultaneous Tumor Imaging and Photothermal Therapy

Abstract

Single-walled carbon nanotubes (SWCNTs) exhibit intrinsic fluorescence and strong optical absorption in the near-infrared (NIR) biological window (0.7-1.4 μm), rendering them ideal for in vivo imaging and photothermal therapy. Advances in SWCNT sorting have led to improved nanoelectronics and are promising for nanomedicine. To date, SWCNTs used in vivo consist of heterogeneous mixtures of nanotubes and only a small subset of chirality nanotubes fluoresces or heats under a NIR laser. Here, we demonstrate that separated (6,5) SWCNTs exchanged into a biocompatible surfactant, C18-PMH-mPEG, are more than 6-fold brighter in photoluminescence on the per mass basis, afford clear tumor imaging, and reach requisite photothermal tumor ablation temperatures with a >10-fold lower injected dose than as-synthesized SWCNT mixtures while exhibiting relatively low (6,5) accumulation in the reticuloendothelial system. The intravenous injection of ∼4 μg of (6,5) SWCNTs per mouse (0.254 mg/kg) for dual imaging/photothermal therapy is, by far, the lowest reported dose for nanoparticle-based in vivo therapeutics.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
