Cancer is the leading cause of death around the world. Tumor-targeted therapy is one of the major areas in cancer research.The rationale behind using targeted delivery is to facilitate or increase the effect of the delivered cargo to the targeted tissue and to reduce unwanted and non-specific effects of it in the surrounding area. Therefore, the first module of our project offers tracing cancer cells using antigen antibody interactions. We have designed a system in which a complex with antibodies attaches to cancer cells specifically and an enzyme system which triggers bacteria to move towards the cancer cells effectively. This complex is also used for quorum sensing molecules to trigger bacterial response. Bacteria will produce this complex then, this complex produced quorum sensing molecule as a feed back at the presence of cancer cells.
