World’s first nano-scale design to mimic natural blood vessels
New materials developed by University of Melbourne researchers stop potentially deadly blood clots forming in the treatment of many cardiovascular diseases.
Fatemeh Karimi, a postdoctoral researcher, and her team have developed a new material that can be used to create artificial veins and arteries with nano-scale design used as replacements in heart and stroke surgery.
Professor Mark Kendall is planning to dispatch the 160-year-old needle and syringe to history. He’s invented a new vaccine technology that’s painless, uses a fraction of the dose, puts the vaccine just under the skin, and doesn’t require a fridge.
The Nanopatch is a 1 cm square piece of silicon with 20,000 microscopic needles engineered on one side. Coat the needles with dry vaccine, push it gently but firmly against the skin, and the vaccine is delivered just under the outer layer of skin.
It’s a technology he invented in response to a call from the Bill and Melinda Gates Foundation seeking ideas for delivery of vaccines in developing countries—where it’s a challenge to keep conventional wet vaccines cold to the point of delivery.
Ultra-thin boron nitride outshines gold and silver when used to detect contaminants in smart sensing technology.
It is 100 times more effective at detecting dangerous materials in our food and environment than noble metals.
Traditionally, detection surfaces of these devices have been made using gold and silver. But covering these metals with a microscopically thin layer of boron nitride greatly enhances their performance.
Nanoscale spikes on dragonfly wings are inspiring materials that kill bacteria, including deadly antibiotic-resistant golden staph (Staphylococcus aureus).
Elena Ivanova and her fellow researchers at Swinburne University of Technology were studying self-cleaning surfaces in nature when they discovered bacteria being killed on the wings of the clanger cicada, Psaltoda claripennis, a species mostly found in Queensland.
The secret seemed to lie in millions of tiny rounded spikes, or nanopillars, each a thousand times smaller than the width of a human hair.
Tiny diamonds have been used to track single atoms and molecules inside living cells.
A University of Melbourne team has developed a device that uses nanoscale diamonds to measure the magnetic fields from a living cell’s atoms and molecules, with resolution a million times greater than current magnetic resonance imaging.
