Bacteria fed on a customized diet produce biodegradable polymers for alternative packaging in the cosmetics industry

Replacing harmful solvents with pressure change technology

06-Oct-2020

Germany generates around 38 kilograms of plastic waste per capita each year. In a joint project with the University of Stuttgart and LCS Life Cycle Simulation, researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and the Fraunhofer Institute for Process ...

What Do Spiders Have in Common with Batteries?

Spider silk inspires new class of functional synthetic polymers: Conducting protein-based material could be used in fuel cells, batteries or act as sensor

14-Aug-2020

Synthetic polymers have changed the world around us, and it would be hard to imagine a world without them. However, they do have their problems. It is for instance hard from a synthetic point of view to precisely control their molecular structure. This makes it harder to finely tune some of their ...

Bioplastics from Waste Fats

Using bacteria to replace plastics derived from fossil oil

25-Sep-2019

450 million tons of plastic are produced globally each year. PHAs represent a tentative approach to defeating the plague that is plastic. PHA stands for Polyhydroxyalkanoates. Polyhydroxyalkanoates are biopolymers and are referred to as bioplastics due to the similarity of their thermoplastic ...

Nanodiamonds in the brain

Tiny diamonds can cross the blood-brain barrier and be used for diagnostic and therapeutic purposes in the brain

03-Sep-2019

The recording of images of the human brain and its therapy in neurodegenerative diseases is still a major challenge in current medical research. The so-called blood-brain barrier, a kind of filter system of the body between the blood system and the central nervous system, constrains the supply of ...

New flexible, transparent, wearable biopatch, improves cellular observation, drug delivery

Minimally invasive patch delivers exact doses directly into cells, lessens pain, toxicity

12-Nov-2018

Purdue University researchers have developed a new flexible and translucent base for silicon nanoneedle patches to deliver exact doses of biomolecules directly into cells and expand observational opportunities."This means that eight or nine silicon nanoneedles can be injected into a single cell ...

A path to sustainable and biodegradable polyesters

04-Jun-2018

There's a good chance you've touched something made out of the polyolefin polymer today. It's often used in polyethylene products like plastic bags or polypropylene products like diapers. As useful as polyolefins are in society, they continue to multiply as trash in the environment. Scientists ...

Modified biomaterials self-assemble on temperature cues

21-Mar-2018

Biomedical engineers from Duke University have demonstrated a new approach to making self-assembled biomaterials that relies on protein modifications and temperature. The hybrid approach allows researchers to control self-assembly more precisely, which may prove useful for a variety of biomedical ...

Lifesaving Microbubbles

Stable, self-disrupting microbubbles as intravenous oxygen carriers

24-Jan-2018

Severe oxygen deficiency eventually leads to cardiac arrest. If the blood’s oxygen content cannot be rapidly re-established, the patient may die within minutes. American scientists have introduced air-filled microbubbles that could be used as an intravenous oxygen carrier to increase the survival ...

Multifunctional nano-sized drug carriers based on reactive polypept(o)ides

15-Sep-2017

In cooperation with researchers from the University of Tokyo and Gutenberg Research Awardee Prof. Kazunori Kataoka, Chemists from Mainz have been able to demonstrate that reactive polypept(o)ides constitute ideal building blocks to control morphology and function of carrier systems in a simple ...

Ecology insights improve plant biomass degradation by microorganisms

27-Jun-2017

Microbes are widely used to break down plant biomass into sugars, which can be used as sustainable building blocks for novel biocompounds. Getting the right microbial community for this process is still a matter of trial and error. New insights by University of Groningen microbial ecologist Dr ...
