Pores with a Memory

Porous polymer films with shape memory

08-Feb-2018

Whether for separation processes, photovoltaics, catalysis, or electronics, porous polymer membranes are needed in many fields. Membranes with micropores that switch between different shapes and/or sizes would expand the possibilities. Scientists have introduced a process that produces porous ...

Fast-tracking T cell therapies with immune-mimicking biomaterials

17-Jan-2018

Immunologists and oncologists are harnessing the body's immune system to fight cancers and other diseases with adoptive cell transfer techniques. In a normal immune response, a type of white blood cell known as T cells are instructed by another kind of immune cell called an antigen-presenting ...

One step ahead towards the artificial heart

09-Nov-2017

An artificial heart would be an absolute lifesaver for people with cardiac failure. However, to recreate the complex organ in the laboratory, one would first need to work out how to grow multi-layered, living tissues. Researchers at Empa have now come one step closer to this goal: by means of a ...

Nanoparticles from the secretion of velvet worms form polymer fibres that can be recycled in water

18-Oct-2017

Nature is an excellent teacher – even for material scientists. Researchers, including scientists at the Max Planck Institute of Colloids and Interfaces, have now observed a remarkable mechanism by which polymer materials are formed. In order to capture prey, velvet worms shoot out a sticky ...

Simple Biomechanical Test could aid Implant Success

Deeper insight into potential interaction between implants and body tissues

11-Oct-2017

The quality of the tissue-implant interface is key to the success of implant integration. High-output benchtop screening can help developers in assessing the complex interplay between biomaterials and the body to better prepare for clinical trials.High-output screening aims to maximize the amount ...

How bacteria maintain and recover their shape

31-Jul-2017

Bacteria come in all shapes and sizes -- some are straight as a rod, others twist like a corkscrew. Shape plays an important role in how bacteria infiltrate and attack cells in the body. The helical shape of Helicobacter pylori, a species of bacteria which can cause ulcers, may help it penetrate ...

No sugar coating, but sweet nonetheless

First long-term stabile brain implant developed based on an anti-inflammatory coating

07-Apr-2017

Complex neurotechnological devices are required to directly select and influence brain waves inside the skull’s interior. Although it has become relatively easy to implement the devices, researchers are still faced with challenges when trying to keep them running properly in living organisms over ...
