Abstract

BACKGROUND: Effective delivery of photosensitizer to target tumor cells that causes minimal damage to healthy cells is an important requirement in photodynamic therapy of cancer. AIM: We aimed to use biocompatible gold nanoparticles as a vehicle to deliver 5-aminolevulinic (5-ALA) acid for selective and efficient photodynamic therapy. RESULTS: Protoporphyrin IX accumulated preferentially in fibrosarcoma tumor cells treated with 5-ALA-conjugated nanoparticles while yielding significantly higher reactive oxygen species compared with that with 5-ALA. The elevation of reactive oxygen species resulted in 50% more cytotoxicity to tumor cells than that of 5-ALA alone. Selective destruction of tumor cells was also achieved using 5-ALA-conjugated nanoparticles in co-culture with dermal fibroblasts. CONCLUSIONS: 5-ALA-conjugated nanoparticles offer a new modality for selective and efficient destruction of tumor cells, with minimal damage to fibroblasts in the 5-ALA-photodynamic therapy.

  • Conjugating 5-aminolevulinic acid to nanoparticles, including biocompatible gold (Au) and chitosan, was suggested to improve ALA delivery to the tumor.

    “Conjugating 5-aminolevulinic acid to nanoparticles, including biocompatible gold (Au) and chitosan, was one of the solutions suggested to improve ALA delivery to the tumor [78,79].”

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.
