The Nobel laureate Richard Feynman first presented the idea of nanotechnology in his lecture “There's Plenty of Room at the Bottom”.¹  After more than half a century, it is clear that this still-young field has led to a revolutionary shift in the way we understand and apply materials science. Moreover, the increasing expertise in nanoscience has allowed a great deal of progress in many different areas, for example agriculture and water management,^2–4  flexible electronics,⁵  environmental remediation⁶  and transportation,⁷  among others.

One of the most enriched fields by these advancements is biomedicine. Nanotechnology has played a...
