Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers
Advanced Functional Materials, EarlyView.Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

Acoustically propelled nanoshells
Nanoscale, 2016 Herein we report a new design for acoustic nanoswimmers, making use of a nanoshell geometry that was synthesized using a sphere template process. Such shell-shaped nanomotors display highly efficient acoustic propulsion on the nanoscale by converting energy from the ambient acoustic field into motion.
