Sentinel lymph nodes (SLNs) represent the sites where micro-metastasis can first develop, however they are also important to mount effective anti-tumor immune responses. Here the authors describe the design of a flex-patch loaded with anti-PD-1 antibodies and immuno-adjuvant nanosheets, layered double hydroxide, to fuel anti-tumor immune response in the SLN for postsurgical breast cancer adjuvant therapy.
