Upconversion Nanoparticles for Photodynamic Therapy and Other Cancer Therapeutics

  title={Upconversion Nanoparticles for Photodynamic Therapy and Other Cancer Therapeutics},
  author={Chao Wang and Liang Cheng and Zhuang Liu},
Photodynamic therapy (PDT) is a non-invasive treatment modality for a variety of diseases including cancer. PDT based on upconversion nanoparticles (UCNPs) has received much attention in recent years. Under near-infrared (NIR) light excitation, UCNPs are able to emit high-energy visible light, which can activate surrounding photosensitizer (PS) molecules to produce singlet oxygen and kill cancer cells. Owing to the high tissue penetration ability of NIR light, NIR-excited UCNPs can be used to… CONTINUE READING
