Abstract Micro/nanorobots hold exciting prospects for biomedical and even clinical applications due to their small size high controllability. However, it is still a big challenge maneuver micro/nanorobots into narrow spaces with deformability adaptability perform complicated tasks. Here, we report light-controlled soft bio-microrobots (called “Ebot”) based on Euglena gracilis that are capable of performing multiple tasks in microenvironments including intestinal mucosa controllability, adaptability. The motion the Ebot can be precisely navigated via polygonal flagellum beating. Moreover, shows highly controlled different light illumination duration, which allows pass through curved microchannels With these features, Ebots able execute tasks, such as targeted drug delivery, selective removal diseased cells mucosa, well photodynamic therapy. This provides new bio-microrobotic tool, many possibilities task execution where conventional tools difficult access lack bio-adaptability.

Micro/nanorobotic swarms consisting of numerous tiny building blocks show great potential in biomedical applications because their collective active delivery ability, enhanced imaging contrast, and environment-adaptive capability. However, vivo real-time tracking micro/nanorobotic remain a challenge, considering the limited size spatial-temporal resolution current modalities. Here, we propose strategy that enables navigation microswarm stagnant flowing blood environments by using laser speckle contrast (LSCI), featuring full-field imaging, high temporal-spatial resolution, noninvasiveness. The change dynamic convection induced can be quantitatively investigated analyzing perfusion unit (PU) distribution, offering an alternative approach to investigate swarm behavior its interaction with various environments. Both surrounding environment were monitored imaged LSCI real time, images further analyzed for simultaneous complex vascular system. Moreover, our realized vivo, showing promising LSCI-guided

A biofilm constitutes a bacterial community encased in sticky matrix of extracellular polymeric substances. These intricate microbial communities adhere to various host surfaces such as hard and soft tissues well indwelling medical devices. aggregates form robust substances (EPSs), leading the majority human infections. Such infections tend exhibit high resistance treatment, often progressing into chronic states. The EPS protects bacteria from hostile environment prevents penetration antibacterial agents. Modern robots at nano, micro, millimeter scales are highly attractive candidates for biomedical applications due their diverse functionalities, navigating confined spaces targeted multitasking. In this tutorial review, we describe key milestones strategies developed removal eradication biofilms using different sizes shapes.

Microalgae provide autonomous propulsion lungs, leveraging controlled drug release enhanced dispersion exert antimetastatic effects. Upon intratracheal administration, algae-NP(DOX)-robots efficiently transport their payload deep into lungs while maintaining continuous motility. This strategy leads rapid distribution, improved tissue accumulation, prolonged retention compared passive free controls.
