Photothermal and radiotherapy with alginate-coated gold nanoparticles for breast cancer treatment.

Radiation therapy and phototherapy are commonly used cancer treatments that offer advantages such as a low risk of adverse effects and the ability to target cancer cells while sparing healthy tissue.
