min, which is currently difficult to achieve with other traditional methods. This research is an innovation in the field of dental surgery. Due to the autonomousmotion and the tiny size of the microrobots, it is reasonable to believe that it will also have a significant impact in other medical fields

of detection as low as 2.4 ng mL−1 TNT within 1 minute. Such bubble-propelled Janus UCNP capsule motors have great potential for contaminated water analysis.

the Janus UCNP capsule motors were successfully prepared.
The autonomousmotion of the Janus UCNP capsule motors was recorded by using microscopy. To better explore the movement behaviour of the Janus UCNP capsule motors, the corresponding motion trajectories, speed, and oxygen bubble frequency were
. Benefiting from the enhanced autonomousmotion, the LOD of the Janus UCNP capsule motors (2.4 ng mL−1) is 3.5 times better than that of static UCNPs within shorter analysis time. Such a micromotor could be used as a multifunctional platform integrating autonomousmotion and TNT detection for efficient and
