Abstract: S1.00146 : CuS Nanoparticles for Photothermal Ablation of Tumor Cells
Author:
Here, we report the photothermal ablation effects of 3-nm CuS
nanoparticles.
CuS nanoparticles exhibited strong absorption in the near
infrared (NIR)
region. Irradiation by a laser beam at 808 nm elevated the
temperature of
aqueous solutions of CuS nanoparticles as a function of exposure
time and
nanoparticle concentration. CuS nanoparticles mediated photothermal
destruction of HeLa cells in a laser dose- and nanoparticle
concentration-dependent manner, and displayed minimal cytotoxic
effects with
a profile similar to that of gold nanoparticles. Owing to their
unique
optical property, small size, low cost of production, and low
cytotoxicity,
CuS nanoparticles are promising new nanomaterials for cancer
photothermal
ablation therapy.
