Micromotors are powered by bacteria, controlled by light

(Phys.org)—When researchers deposit a drop of fluid containing thousands of free-swimming, genetically engineered E. coli onto an array of micromotors, within minutes the micromotors begin rotating. Some of the individual ...

'Ferropaper' is new technology for small motors, robots

(PhysOrg.com) -- Researchers at Purdue University have created a magnetic "ferropaper" that might be used to make low-cost "micromotors" for surgical instruments, tiny tweezers to study cells and miniature speakers.

Microspiders: Polymerization reaction drives micromotors

(PhysOrg.com) -- Though it seems like science fiction, microscopic "factories" in which nanomachines produce tiny structures for miniaturized components or nanorobots that destroy tumor cells within the body and scrape blockages ...

Researchers Turn Classic Children's Toy Into Tiny Motor

Researchers at the University of Texas at Austin have miniaturized a children's toy into a tiny motor that could one day power medical devices or harvest solar energy. The device, called a radiometer, is based on a classical ...

Nano- and micromotors for biological and chemical applications

Nano- and micromotors are ultra-small devices designed to perform selected mechanical movements in response to specific stimuli. These movements include rotation, rolling, shuttling, delivery, contraction or collective behaviour, ...

New water treatment method can generate green energy

Researchers from ICIQ in Spain have designed micromotors that move around on their own to purify wastewater. The process creates ammonia, which can serve as a green energy source. Now, an AI method developed at the University ...

Micromotors for energy generation

Hydrogen is considered to be the energy source of the future: the first vehicles powered by hydrogen fuel cells are already on the market. However, the problem of hydrogen storage has not been solved in a satisfactory way. ...

Another step toward an insulin tablet

For the millions of people living with diabetes, insulin is a life-saving drug. Unlike many other medicines, though, insulin cannot be easily delivered by swallowing a pill—it needs to be injected under the skin with a ...
