A robot smaller than a single bacterium can now chase down, capture, transport, and release live microbes in water, all ...

Bacteria-scale robots that can run for months without human control are no longer a lab fantasy. Researchers have now built fully programmable micro-machines, smaller than a grain of salt, that can ...

Engineers attempting to build microscopic robots face a strict physical trade-off: as mechanical devices shrink, their ...

Magnetic soft robots deliver and release tens of millions of probiotic bacteria with timed control, disrupt tumor spheroids in vitro, and demonstrate a potential strategy for targeted cancer treatment ...

When bacteria infect our bodies, they sometimes form sticky mats of sugars and proteins called biofilms to protect themselves. This viscous layer makes it difficult for antibiotics and immune cells to ...

Tiny magnetic bots that are activated by light can clear bacterial infections deep in the sinus cavities, then be expelled by blowing out the nose. Sinusitis is a common respiratory condition often ...
