Chemo-physical Strategies to Advance the Functionality of Targeted Nanomedicine: The Next Generation.

The past few decades have witnessed an evolution of nanomedicine from biologically inert entities to more smart systems, aimed at advancing functionality. However, we should recognize that most systems still rely on reasonable explanation-including some over-explanation-rather than definitive evidence, which is a watershed radically determining the speed and extent of advancing nanomedicine. Probing nano-bio interactions and desirable functionality at the tissue, cellular, and molecular levels is most frequently overlooked. Progress toward answering these questions will provide instructive insight guiding more effective chemo-physical strategies. Thus, in the next generation, we argue that much effort should be made to provide definitive evidence for proof-of-, in lieu of creating many new and complicated systems for similar proof-of-.
