Cancer treatment has benefited significantly from the unique properties of gold nanoparticles. Their ability to interact with biological tissues and external energy sources enables innovative therapeutic approaches.

Photothermal therapy is one of the most promising applications. When exposed to specific light wavelengths, gold nanoparticles convert light into heat, selectively destroying cancer cells while minimizing damage to surrounding healthy tissue.

Gold nanoparticles also support combination therapies. They can simultaneously deliver drugs and enhance radiation or thermal treatments, increasing overall therapeutic impact.

Tumor targeting is improved through surface functionalization, allowing gold nanoparticles to accumulate preferentially in cancerous tissues. This specificity enhances treatment precision and reduces systemic exposure.

These advancements position gold nanoparticles as valuable tools in the evolution of cancer care strategies.
