Portable gel could save an injured eye
When a soldier sustains a traumatic eye injury on the battlefield, any delay in treatment may lead to permanent vision loss. With medical facilities potentially far away and no existing tools to prevent deterioration, medics are in a high-stakes race against the clock. A multidisciplinary team of scientists and engineers at USC are close to solving the problem. They have developed a reversible, temperature-sensitive temporary seal that chang...
Heart model helps 16-year-old heart tumour patient
It’s devastating news when you find out that your grandchild was born with a heart tumour. This was the news that Christine White heard when her grandson, Bradley, was only three. Over the next several years, Bradley had to undergo several open heart surgeries including having a defibrillator implanted to protect him from sudden cardiac death.
3D printing lifelike artificial organ models
A team of researchers led by the University of Minnesota has 3D printed lifelike artificial organ models that mimic the exact anatomical structure, mechanical properties, and look and feel of real organs. These patient-specific organ models, which include integrated soft sensors, can be used for practice surgeries to improve surgical outcomes in thousands of patients worldwide. The research was published in the journal Advanced Material...
'Living tattoo': 3D printing programmed cells into devices
MIT engineers have devised a 3D printing technique that uses a new kind of ink made from genetically programmed living cells. The cells are engineered to light up in response to a variety of stimuli. When mixed with a slurry of hydrogel and nutrients, the cells can be printed, layer by layer, to form 3D, interactive structures and devices. The team has then demonstrated its technique by printing a “living tattoo” &mdash...
Low-cost jaundice detector passes first test in Africa
The first clinical study of a low-cost, hand-held jaundice detector invented by Rice University students couldn’t have come at a better time for NEST360°, an international team of scientists, doctors and global health experts preparing for a competition for $100 million from the MacArthur Foundation. The money would allow the team to carry out its visionary plan to halve the number of newborn deaths in African hospitals within 10 years.
Building virus-sized structures through mass production
It is the double strands of our genes that make them so strong. Using a technique known as DNA origami, biophysicist Hendrik Dietz has been building nanometer-scale objects for several years at the Technical University of Munich (TUM). Now Dietz and his team have not only broken out of the nanometer realm to build larger objects, but have also cut the production costs a thousand-fold. These innovations open a whole new frontier for the ...
Orthopaedic product has the potential to improve bone apposition
Omnia Medical VBR has been granted the first US FDA 510(k) clearance for a vertebral body replacement (VBR) system manufactured from PEEK-OPTIMA HA Enhanced polymer, from Invibio Biomaterial Solutions, for use in the thoracolumbar spine to replace a collapsed, damaged, or unstable vertebral body.
Breast imaging could reduce false positive examinations
Seno Medical Instruments, Inc. has announced positive data from PIONEER, a Phase III pivotal trial of its Imagio breast imaging system. The study found that OA/US was more specific than device gray-scale ultrasound alone (US) in differentiating malignant from benign breast lesions and was non-inferior to US with respect to sensitivity. This means that OA/US detected a similar number of malignant lesions as US but had a lower rate of false po...
Forming a bioactive spider silk for medical use
With recent advances, technology can be used to synthesise silk with similar mechanical properties as an actual spider’s. But applying this material to promising medical therapies for illnesses such as cancer requires that humans develop a capability that only arachnids or silkworms possess – the ability to control the formation of silk.
Biocompatible ink for 3D printing makes use of living bacteria
A group of ETH researchers led by Professor André Studart, Head of the Laboratory for Complex Materials, has now introduced a 3D printing platform that works using living matter. The researchers developed a bacteria-containing ink that makes it possible to print mini biochemical factories with certain properties, depending on which species of bacteria the scientists put in the ink.
