New integrated biomaterial risk assessment testing system

01/08/2018

PANBioRA is a four-year "Research and Innovation Action" funded by the European Union’s Horizon 2020 programme aiming to develop a modular system using cross-disciplinary techniques that will predict the patient-specific response to a given biomaterial and methods for analysing novel biomaterials. After six months new advances in different aspects of the system have been reached in the project.

Detecting Parkinson's with sensors and nanoparticles

27/07/2018

Symptoms of Parkinson's disease include tremor, loss of smell and neuropsychiatric problems. However, many people aren't diagnosed until their disease is well-advanced, which could limit their treatment options.

Targeting headaches and tumors with nano-submarines

26/07/2018

Scientists at the Mainz University Medical Center and the Max Planck Institute for Polymer Research (MPI-P) have developed a new method to enable miniature drug-filled nanocarriers to dock on to immune cells, which in turn attack tumors. In the future, this may lead to targeted treatment that can largely eliminate damage to healthy tissue.

A molecular label: traceability for medical implants

10/07/2018

A team of researchers at CNRS, Aix-Marseille Université and Université Paris 13 has demonstrated effective molecular labelling to unequivocally identify biomedical implants, even after a prolonged period inside the living being. These results were published in Angewandte Chemie International Edition on July 5, 2018.

New 'e-dermis' brings sense of touch to prosthetic hands

06/07/2018

Amputees often experience the sensation of a "phantom limb" – a feeling that a missing body part is still there. That sensory illusion is closer to becoming a reality thanks to a team of engineers at the Johns Hopkins University that has created an electronic skin. When layered on top of prosthetic hands, this e-dermis brings back a real sense of touch through the fingertips.

New headset scans the user's eye movements

05/07/2018

People with disabilities such as ALS, spinal injury or Lou Gehrig's disease, often lose use of their legs, arms or hands. Even at advanced stages of the disease, one may still retain movement in their eyes. Some technologies have incorporated eye-tracking to enable disabled persons to interact with a computer to communicate messages to a caregiver.

Using gold nanoparticles to trigger sequential unfolding of 3D structures

29/06/2018

Researchers from North Carolina State University have developed a new technique that takes advantage of gold nanoparticles to trigger the sequential unfolding of three-dimensional structures using different wavelengths of light.

Electronic skin stretched to new limits

28/06/2018

An electrically conductive hydrogel that takes stretchability, self-healing and strain sensitivity to new limits has been developed at KAUST. "Our material outperforms all previously reported hydrogels and introduces new functionalities," says Husam Alshareef, professor of materials science and engineering.

'Smart stent' detects narrowing of arteries

26/06/2018

For every three individuals who have had a stent implanted to keep clogged arteries open and prevent a heart attack, at least one will experience restenosis - the renewed narrowing of the artery due to plaque buildup or scarring - which can lead to additional complications.

Biological light sensor filmed in action

22/06/2018

Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. In doing so, they produced a molecular movie that reveals how the light sensor retinal is activated in a protein molecule. Such reactions occur in numerous organisms that use the information or energy content of light.

A webcam is enough to produce a real-time 3D model of a moving hand

21/06/2018

Capturing hand and finger movements within milliseconds is becoming increasingly important for many applications, from virtual reality to human-machine interaction and Industry 4.0. So far, it has required enormous technical effort, which in turn has limited the possible applications.

Novel microscopy technique developed to analyze cellular focal adhesion dynamics

20/06/2018

Focal adhesions are large specialized proteins that are located in the area where a cell membrane meets the extracellular matrix (ECM), a collection of molecules surrounding the cells that provide support and regulate micromechanical signals to the cells.

Biomaterial particles educate immune system to accept transplanted islets

19/06/2018

By instructing key immune system cells to accept transplanted insulin-producing islets, researchers have opened a potentially new pathway for treating type 1 diabetes. If the approach is ultimately successful in humans, it could allow type 1 diabetes to be treated without the long-term complications of immune system suppression.
