The delivery of medical agents to a specific diseased tissue or cell is critical for diagnosing and treating patients. Nanomaterials are promising vehicles to transport agents that include drugs, contrast agents, immunotherapies and gene editors. They can be engineered to have different physical and chemical properties that influence their interactions with their biological environments and delivery destinations. In this Review Article, we discuss nanoparticle delivery systems and how the biology of disease should inform their design. We propose developing a framework for building optimal delivery systems that uses nanoparticle–biological interaction data and computational analyses to guide future nanomaterial designs and delivery strategies. This Review proposes a framework for designing delivery systems to target diseased tissues based on the biology of the target, the journey and computational algorithms.
