Tiny Materials, Stronger Antitumor Immunity
 Cancer immunotherapy has changed the treatment landscape, yet many tumors still evade immune attack by hiding antigens, blocking T cell entry, and building an immunosuppressive tumor microenvironment (TME). A new review brings these scattered barriers into one mechanistic framework, showing how engineered nanomaterials can be designed to intervene across the cancer-immunity cycle. Rather than acting only as drug carriers, nanoparticles (NPs) can help deliver antigens and immune stimulants, improve antigen presentation, support T cell priming and infiltration, and reshape hostile tumor niches. The review provides a practical design map for developing more precise, durable, and safer nano-immunotherapies.
