Abstract: Utilizing the body's immune system to combat cancer has become a viable tactic
known as cancer immunotherapy. Metallic nanoparticles, or MNPs, have drawn a lot of interest
because of their special qualities and their uses in cancer immunotherapy. The manufacturing
processes of MNPs, their function in altering the tumor microenvironment (TME), and their capacity
to control immune cells for potent anticancer effects are all thoroughly covered in this
review. The review underscores the benefits of MNPs in surmounting obstacles linked to traditional
cancer treatments, including toxicity, resistance, and off-target effects. It also goes over the
different ways that MNPs modulate the immune system, For example, by generating reactive
oxygen species (ROS), reducing glutathione (GSH) levels, and improving hypoxia. The research
also examines the ability of MNPs to enhance the maturation of dendritic cells, shift macrophages
towards an M1 phenotype, stimulate T-cell responses, and aid in the transportation of natural
killer (NK) cells. The investigation is focused on understanding the synergistic effects of MNPsIn
conjunction with other immunotherapeutic approaches, such as checkpoint inhibitors and
cell-based treatments, in order to generate potent immune responses against cancer.
