Micromotors deliver oral vaccines

Vaccines have saved millions of lives, but nobody likes getting a shot. That's why scientists are trying to develop oral vaccines for infectious diseases. But to be effective, the vaccine must survive digestion and reach ...

A pill for delivering biomedical micromotors

Using tiny micromotors to diagnose and treat disease in the human body could soon be a reality. But keeping these devices intact as they travel through the body remains a hurdle. Now in a study appearing in ACS Nano, scientists ...

Micromotors made easy

Researchers of the ICN2 Nanobioelectronics and Biosensors Group led by Prof. Arben Merkoçi have devised a simple manufacturing method for versatile graphene oxide-based micromotors. Requiring no special equipment, it can ...

Manganese dioxide shows potential in micromotors

Manganese dioxide could make the preparation of micromotors increasingly cost-effective, opening up new avenues for their use, according to a new study from the University of Eastern Finland.

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 ...

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. ...

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, ...
