Our team is inspired by the use of robots which perform tasks that would otherwise be difficult to accomplish. For example, the Mars rovers allow us to make observations and conduct physical experiments in harsh, remote locations otherwise inaccessible to humans. In many ways, the human body represents unexplored territory of a different scale. For example, we may understand many aspects of human disease. However, certain markers of disease are extremely difficult to detect (e.g., primary tumors) and treatment of disease can be hampered by the impracticality of performing invasive surgeries.
The "holy grail" of nanomedicine would be to develop microscopic robots that could travel anywhere in the body and perform complex, user-defined tasks. Such devices would have several key advantages over traditional, small-molecule therapies:
- they could home to specific locations in the body (minimize off-target effects)
- they could make decisions based on their external environment
- they could perform more complicated functions
While the idea of microscopic, therapeutic robots may seem far-fetched, there are examples in such machines in nature. For example, neutrophils (a type of white blood cell) are capable of
- detecting and homing to a wide range of chemical signals, at times localizing to very specific sites of inflammation
- triggering a variety of different pathways (extravasation, phagocytosis, apoptosis) in response to external signals
- navigating through different types of barriers (endothelial tissue, blood-brain barrier, etc)
Taking cues from nature, we are interested in harnessing, or hijacking the function of complicated, natural cellular robots such as neutrophils.
