 Gold nanoparticles, ONPs, have been explored as promising drug delivery vehicles for cancer immunotherapy due to their unique physical and chemical properties. These particles can be used to load drugs or other biologically active molecules, such as antibodies, onto their surfaces, which can then be used to target tumors. Additionally, ONPs can be designed to release their cargo at specific times and locations in order to maximize the effectiveness of the treatment. ONPs have shown promise in improving the precision of cancer treatments by enhancing the immune system's ability to recognize and destroy cancer cells.
