3-D-printed structures "remember" their shapes

29/08/2016

Engineers from MIT and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that "remember" their original shapes.

Wound dressings made from bacterial alginate

10/08/2016

Researchers have succeeded in mapping out for the first time a complete production and treatment process, from using biotechnology to produce bacterial alginate, right through to producing fibres and manufacturing textile materials.

New biomaterial developed for injectable neuronal control

15/07/2016

Ideally, injectable or implantable medical devices should not only be small and electrically functional, they should be soft, like the body tissues with which they interact. Scientists from two UChicago labs set out to see if they could design a material with all three of those properties.

Textiles used in hospitals and medical offices – germs don’t stand a chance

01/06/2016

Some hospitals have long banned the status symbol of physicians – the white coat. Research has shown that especially the sleeves were contaminated with various types of bacteria. But it’s not just lab coats that can spread germs in healthcare settings. This field uses a variety of different textiles. Wouldn’t it, therefore, make sense to apply antimicrobial finishes?

Safe or Not Safe? "The AB-DES has not gained market access in countries like Japan or the U.S."

01/05/2016

Antibody-coated, drug-eluting stents (AB-DES) feature an exterior coated with immunosuppressant drugs and an interior that is coated with antibodies to accelerate the adhesion of endothelial cells. In theory, this makes it possible to shorten the duration of therapy with blood thinners, which can mean relief for patients from an already difficult situation.

Melt electrospinning writing: polymer fibers for tissue engineering

01/02/2016

Sometimes, soft tissue in our body needs to be replaced after surgery or an injury. But surgeons are not always able to take tissue from other body parts as a replacement. Then, they need to use implants. The production of soft implants that can constantly endure load and stress like our own tissue is a big challenge for research. Melt electrospinning writing can be a solution.

Theranostics: Complex particles for tomorrow's medicine

01/10/2015

It is a portmanteau, a mixture of two words. This way it saves us time and trouble while speaking because the human speech apparatus is lazy. And it describes a mixture of procedures: the combination of two procedures that would normally be separate in medicine. We are talking about theranostics.

Stents: Braiding versus cutting

22/05/2015

Braided stents are nothing new in medicine, but their manufacturing process is still time-consuming. This is why Professor Stefan Jockenhövel from the RWTH Aachen University and his team want to make machine production possible.

Gently administering drugs with a membrane containing active ingredients

09/02/2015

Injections are not popular with either children or adults. For years, researchers have therefore been looking for a way to administer drugs in a gentler manner. Swiss scientists now developed a membrane that releases active ingredients under ultraviolet light. It could revolutionize how drugs and vaccines are being administered.
