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).
