Smart insulin patch could replace injections for diabetes

The patch - a thin square no bigger than a penny - is covered with more than one hundred tiny needles, each about the size of an eyelash. These microneedles are packed with microscopic storage units for insulin and glucose-sensing enzymes that rapidly release their cargo when blood sugar levels get too high.

Nanowire implants offer remote-controlled drug delivery

A team of researchers has created a new implantable drug-delivery system using nanowires that can be wirelessly controlled.

Nanobiosensor designed to detect herbicides can help diagnose multiple sclerosis

The early diagnosis of certain types of cancer and nervous system diseases may soon be facilitated by the use of a new detection device.

Robust new process forms 3-D shapes from flat sheets of graphene

Researchers have developed a new approach for forming 3D shapes from flat, 2D sheets of graphene, paving the way for future integrated systems of graphene-MEMS hybrid devices and flexible electronics.

Can heat be controlled as waves?

A progress article describes recent developments and predicts future advances in phonon wave interference and thermal bandgap materials.

New technique for 'seeing' ions at work in a supercapacitor

A new technique which enables researchers to visualise the activity of individual ions inside battery-like devices called supercapacitors, could enable greater control over their properties and improve their performance in high-power applications.

Single-nanocatalyst water splitter produces clean-burning hydrogen 24/7

Scientists have invented a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas 24 hours a day, seven days a week. The device could provide a renewable source of clean-burning hydrogen fuel for transportation and industry.
