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.

Vastly improved medical imaging and guaranteed secure communications are a step closer following a funding boost of more than GBP700,000 in new quantum technology projects at Lancaster University.

2D titanium trisulfide's properties show promise

One completed a series of theoretical calculations to predict its properties with the help of a massive computing center. The other grew it in bulk before waxing its atom-thin whiskers with the assistance of adhesive tape.

Scientists present III-V epitaxy and integration to go below 14nm

Scientists have unveiled a breakthrough approach in two publications for growing and integrating nano-sized III-V semiconductor devices on silicon. Both papers offer the microelectronics industry a possible answer to the long term challenge of creating a new powerful and energy efficient, yet smaller transistor to pave path for technology scaling for advanced CMOS nodes.

Kirigami art could enable stretchable plasma screens

In the future, a little bend in your smartphone might be considered a feature rather than a defect. An important component of future electronics that can be rolled up, folded or embedded in flexible objects is the stretchable conductor, which would make up components like wires and electrodes.
