Over the past two decades, nanomedicine has grown steadily, however, without inducing a palpable shift in the diagnosis and treatment of diseases so far. While this may simply be a consequence of the slow, incremental nature that characterizes many modern technologies, this article posits that there is another set of significant factors harboring explanatory power. Uncertainties concerning safety, regulatory, and ethical requirements may have prompted innovators to stay close to the known and approved, eventually at the cost of innovating in unexplored alleys. Network analysis of all nanomedicine patents in the United States reveals that nanomedicine has indeed rather consolidated than expanded. We detail a set of recommendations that would reduce the uncertainty prevailing in nanomedicine and could contribute to pushing new boundaries.This article is categorized under:Toxicology and Regulatory Issues in Nanomedicine > Regulatory and Policy Issues in Nanomedicine
