These new 3D-printed corneas could help 15 million people see again

  These new 3D-printed corneas could help 15 million people see again A team of English researchers have developed a novel piece of biotechnology that could wind up helping millions get their eyesight back. It’s another marvel…It’s another marvel of three-dimensional printing, using stem cells, collagen, and a type of polysaccharide called alginate to create a so-called “bio-ink” that can be used to print a cornea. It’s not yet on the market, but if approved it would constitute a breakthrough in the field of corneal transplantation, which currently relies on a slow process in addition to there not being enough available corneas to return sight to the 15 million people worldwide estimated as needing the procedure.

Dr Tricoli said the sensors could measure very small concentrations of gases coming through your skin and breath called metabolites, allowing doctors to keep track of people's health in real time .

Scientists from The Australian National University have designed tiny optical sensors 50 times thinner than a human hair.

"These ultra-small sensors could be integrated into a watch to literally provide a window on our health," said Associate Professor Antonio Tricoli, leader of the Nanotechnology Research Laboratory at the ANU Research School of Engineering.

"This exciting invention shows that we are on the cusp of designing the next generation of wearable devices that will help people to stay well for longer and lead better lives."

Dr. Tricoli said the sensors could measure very small concentrations of gases coming through your skin and breath called metabolites, allowing doctors to keep track of people's health in real time.

"You could simply use a pulse of light to track these biomarkers of disease – there’d be no need for batteries, wires or large and expensive lab equipment," Dr Tricoli said. "A wearable medical diagnostic device using our optical sensors may one day eliminate the need for blood tests and many other invasive procedures."

Zelio Fusco, a PhD scholar in Dr. Tricoli's lab, said the new sensors had advantages over other types being developed for wearable medical devices because they could detect metabolites in much smaller concentrations and operate at room temperature.

"The beauty of our sensors is that they are super versatile and can be integrated into different technologies for applications ranging from medical diagnosis, farming and space exploration," said Fusco. "Our sensors could be developed to detect whether a plant has a particular disease or a fruit is ripe, for example."

Co-researcher Dr. Mohsen Rahmani said the sensors combined very small gold nanostructures with semiconductors in a way that created unique properties to enable the detection of gas molecules at very low concentrations.

"As the sensors are ultra-small and ultra-light, they could potentially be fitted to micro-satellites or tiny spacecraft that could help in the hunt for life on distant planets, by telling us if there are trace organic molecules of living organisms on distant planets," said Dr Rahmani, an Australian Research Council Discovery Early Career Research Fellow at the ANU Research School of Physics and Engineering.

Glucagon-like peptide-1 (or GLP-1) is a metabolic hormone found in both the venom and the gut of one of the most wonderful and unique creatures on our planet - the platypus. Turns out, it stimulates the release of insulin. The hormone will now be investigated for its potential to treat type 2 diabetes, in new research led by the University of Adelaide.
