Applying precious metal catalysts economically

Researchers at Ruhr-Universität Bochum and the Fritz Haber Institute Berlin have developed a new method of to conserve rare and expensive catalysts and use them sparingly. They enclosed a precious metal salt in tiny micelles, ...

How to pop open soft nanoparticles using sound waves

Ultrasound has long been an important tool for medical imaging. Recently, medical researchers have demonstrated that focused ultrasound waves can also improve the delivery of therapeutic agents such as drugs and genetic material. ...

Nanoparticles can aid in stroke therapy

Tiny selenium particles could have a therapeutic effect on ischemic brain strokes by promoting the recovery of brain damage. Pharmacologists, including Alireza Mashaghi from the Leiden Academic Centre for Drug Research discovered ...

Filming how our immune system kill bacteria

To kill bacteria in the blood, our immune system relies on nanomachines that can open deadly holes in their targets. UCL scientists have now filmed these nanomachines in action, discovering a key bottleneck in the process ...

A new synthetic nanofactory inspired by nature

Bacteria across our planet contain nanometer-sized factories that do many different things. Some make nutrients, others isolate toxic materials that could harm the bacteria. We have barely scratched the surface of their functional ...

Sweating the small stuff

Assistant professor of medical engineering Wei Gao is enriching the field of personalized and precision medicine with an abundant source of chemical data: sweat.

3-D printing of biological tissue

The future of medicine is biological – and scientists hope we will soon be using 3-D-printed biologically functional tissue to replace irreparably damaged tissue in the body. A team of researchers from the Fraunhofer Institute ...

Image: Smart particles

Down to the microscopic level, nanoparticles show promising properties. A team of experts in Italy has spent years tailoring tiny inorganic materials and analysing their behaviour. Some have magnetic properties, others are ...

DNA folds into a smart nanocapsule for drug delivery

Researchers from University of Jyväskylä and Aalto University in Finland have developed a customized DNA nanostructure that can perform a predefined task in human body-like conditions. To do so, the team built a capsule-like ...

Wristbands do a health check while you work out

Next-generation fitness sensors could give deeper insights into human health through noninvasive testing of bodily fluids. A stretchy patch developed at KAUST could help this approach by making it easier to analyze sweat ...
