Nanotherapeutics in oral and parenteral drug delivery: Key learnings and future outlooks as we think small

Schematic representation of nanotherapeutics in the nanorobot avatar. Cancer utilizes complex regulatory networks and nanorobots will seek out and interact with tumor cells using its unique surface functionalization and sensing capabilities for improving immune response. Circulating nanoparticles can interact with dentritic cells and macrophages to activate T cells for improving the immune response.275
