Atomic-Level Nanorings (A-NRs) Therapeutic Agent for Photoacoustic Imaging and Photothermal/Photodynamic Therapy of Cancer
Abstract
Photothermal therapy (PTT) and photodynamic therapy (PDT) have emerged as effective approaches for cancer treatment. Herein, we present atomic-level scale (0.5 nm thickness) ultrathin sulfur-doped molybdenum oxide nanorings (S-MoOx A-NRs) and with surface coating of polyethylene glycol (PEG) (PEG@S-MoOx A-NRs). This nanomaterial shows high absorbance in the near-infrared (NIR) range and can be used as a sensitive photoacoustic imaging (PAI) contrast agent. Upon NIR irradiation, the particles show high photothermal conversion and reactive oxygen species (ROS) generation, which effectively kills cancer cells both in vitro and in vivo. The PEG@S-MoOx A-NRs allow PAI and synergistic PTT/PDT therapy, which is demonstrated as a promising theranostic strategy for future cancer therapy.

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.
