Nanoparticles are widely used in nanomedicine for controlled drug delivery and improved bioavailability. However, their effectiveness is often limited by passive diffusion, especially in confined, fluid-filled environments like the bladder, where rapid drug clearance and uneven distribution reduce therapeutic impact. These challenges contribute to high recurrence in bladder cancer despite intravesical chemotherapy. To address this limitation, we present urease-powered nanomotors (NM) based on me
